i. Number of parameters
ii. Type of parameters
Explanation:When there are two or more constructors, definitely with the same name, in a given class, then the constructors are said to be overloaded. An overloaded constructor appears declared many times in a class but each time with different number of parameters and/or type of parameters.
For example, given a class Test, the following combination of constructors can exist;
i. public Test(int x){
}
ii. public Test(String m){
}
iii. public Test(int a, String b){
}
The following should be noted;
In the case of combination (i) and (ii), the constructors have the same number of parameters but different type of parameter. In other words, they both have 1 parameter but while the first one has a parameter type of int, the second has a parameter type of String.
In the case of combination (ii) and (iii), the constructors have different number of parameters and of course different type of parameters. In other words, the second constructor has 1 parameter of type String while the third constructor has 2 parameters of types int and String.
what's the difference between pseudo code and natural language
Answer:
The pseudo-code describes steps in an algorithm or another system in plain language. Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming.
Natural languages consist of phrases, usually declarative phrases, with a sequence of information.
Explanation:
Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming. It usually omits information that is essential to the understanding of the algorithm by the machine, for example, variable declarations and language code.Easily human, but not machines, use the natural languages (like English).Natural languages also are creative. Poetry, metaphor, and other interpretations are permitted. Programming permits certain style differences, but the significance is not flexible.The aim of using pseudo-code is to make it easier for people to comprehensibly than standard programming language code and to describe the key principles of an algorithm efficiently and environmentally independently. It is usually used for documenting software and other algorithms in textbooks and scientific publications.Regarding the role played by the “victim” in deadlock resolution, give an example of such a deadlock in real life and explain your answers to these questions.
a. Describe how you might choose the victim to be removed and the consequences, both positive and negative, of that removal.
b. Describe the fate of the victim and the chances of eventually completing its processing.
c. Describe the actions required, if any, to complete the victim’s tasks.
Answer:
Here the answer is given as follows,
Explanation:
The real-life situation of a deadlock resolution where a role is played by the victim is given as follows:
Example: An example of such a situation are often a one-way lane where the flow of traffic is merely in a method. Thus, on just one occasion, the flow of traffic can enter one direction only. Each entrance/exit gate is often considered a resource. during this case, if two cars are coming from both the entrances and that they are often considered as two tasks, then one among the cars must copy or we will say hand over its resource in order that the opposite car gets the prospect to first cross the lane or we will say the opposite task gets executed.
a) Victim: The steps which describe how a victim is chosen are given as follows :
The task which is terminated so as to interrupt things of deadlock is taken into account because of the victim.
There are often a variety of job pools that will be under a deadlock situation and therefore the victim is usually a low-priority task in order that the performance isn't affected that much and termination of this task doesn't cause any effect on the opposite jobs.
the main positive effect of selecting and terminating a victim is that things of deadlock are resolved and every one of the tasks can execute now.
The negative effect is that the task that's chosen because the victim is terminated and is executed at the previous. This whole process for choosing a victim then terminating it then restarting it again may consume some longer also.
b) An easy deadlock priority is often set. this suggests that the victim’s task or the task is often terminated so as to interrupt the deadlock and other jobs can finish executing. After this, the task which is terminated are often later restarted and every one of the tasks can then execute without a deadlock.
c) When employment gets terminated, the knowledge associated with it's stored. Are often This is often done in order that the work can be restarted again and therefore the information in it's not lost. Since the progress of the victim is stopped. Thus, the sole thanks to complete the victim’s task would be to start out it again. But before restarting the task, this must be considered that the victim’s task doesn't cause any deadlock within the system.

Can you help me in this question
Answer:
I think the third one (or the one with monkeys).
Explanation:
2+2 does not equal 5, so the if then statement is void because both parts are wrong.
1+1 does not equal 3 even if 2+3 =5, so it is not the second answer.
3+1 does not equal 3, but monkeys do fly and it is an or option, so when one of them is correct in an or, it is correct.

The following program generates an error. Why? #include #include using namespace std; class Arcade { public: Arcade(); Arcade(string name, int r); void Print(); private: string arcName; int rating; }; Arcade:: Arcade() { arcName = "New"; rating = 1; } Arcade:: Arcade(string name, int r) { arcName = name; rating = r; } void Arcade:: Print() { cout << "Name is: " << arcName << endl; cout << "Rating is: " << rating << " stars" << endl; } int main() { Arcade myArc(Games Ablaze, 5); myArc.Print(); }
Answer:
The object creation should be Arcade myArc("Games Ablaze",5);
Explanation:
Required
Why does the program generate an error?
The class definition is correctly defined and implemented;
The methods in the class are also correctly defined and implemented.
The error in the program is from the main method i.e.
int main() {
Arcade myArc('ames Ablaze, 5);
myArc.Print();
}
In the class definition;
Variable name was declared as string and variable rating was declared as integer
This means that, a string variable or value must be passed to name and an integer value or variable to rating.
Having said that:
Arcade myArc(Games Ablaze, 5); passes Games Ablaze as a variable to th function.
Game Ablaze is an incorrect string declaration in C++ because of the space in between Game and Ablaze
Also, no value has been assigned to the variable (assume the variable definition is correct).
This will definitely raise an error.
To correct the error, rewrite the object creation as:
Arcade myArc("Games Ablaze",5); where "Game Ablaze" is passed as string
which feature of organisations to manage needs to know about to build and use information system successfully
The correct answer to this open question is the following.
The feature of organizations to manage needs to know about to build and use information system successful is the following.
Managers of successful organizations should know that companies have hierarchies and different structures in which these companies are organized.
Every company use systems and procedures that could be specialized to the degree the company requires. For that system to function, they have to be perfectly interconnected to all the areas of the company. The goal: to maximize efficiency and accomplish the goals.
Systems and procedures should take into consideration the culture and diversity of the workplace. There are interest groups in every organization that have special characteristics and requirements that have to be taken into consideration to create a much better system.
Good managers must be aware of these elements, and the different roles, goals, management styles, tasks, incentives, and departmental structure of the company so the system can better serve the purpose of the entire organization.
Create a file named A10.java. Place all your code in this file. Create a publicstatic ArrayList of integers named intList.
Define a public static method addNumber(int i) that adds ito your list.
Exercise 2
Create a publicstatic HashMap of integers,integers namedintMap.
Define a public static method addPair(int i,int j) that adds i,jto your HashMap (make ithe key and j the value).
Explanation:
The file named as A10.java has been attached to this response. It contains the source code for the exercises. The source code contains comments explaining important parts of the code.
A few things to note;
i. To add an item to an arraylist, the add() method is used. For example to add an integer 7 to the arraylist named intList, simply write;
intList.add(7);
ii. To add an item to a hashmap, the put() method is used. The put method receives two parameters which are the key and value respectively. The key is a form of identifier used to store or retrieve a particular value in a hashmap. To store an integer 8 with a key of 5 in a hashmap named intMap, for example, simply write;
intMap.put(5,8);
In a paragraph, describe in detail a practical real-world example of where you would implement a singly-linked list and why a singly-linked list is best for this use. Do not list the properties of a singly-linked list....
Rather identify a real-world example or application. If you identify this through research, cite your source.
Answer:
travel
Explanation:
One real world example of a singly-linked list would be travel. Imagine that you want to take a trip to your nearest neighbor state. To do so you would need to take a 2 buses and a train, but you can't just take any or in any order you wish. You first need to take the first bus at your current location, get off at the train station, take that train to the final stop, get off and take the bus to the final destination. Meaning there is a sequence of connected events that you must follow in order to get to your destination and the same opposite sequence of events to get back. This is exactly like a singly-linked list.
After the explosion of the Union Carbide plant the fire brigade began to spray a curtain of water in the air to knock down the cloud of gas.a. The system of water spray pipes was too high to helpb. The system of water spray pipes was too low to helpc. The system of water spray pipes broked. The system of water spray pipes did not have sufficient water supply
Answer:
d. The system of water spray pipes did not have sufficient water supply
Explanation:
The Union Carbide India Ltd. was chemical factory situated at Bhopal that produces various pesticides, batteries, plastics, welding equipment, etc. The plant in Bhopal produces pesticides. In the year 1984, on the night of 2nd December, a devastating disaster occurred on the Bhopal plant which killed millions of people due to the leakage of the poisonous, methyl isocyanate. This disaster is known as Bhopal Gas tragedy.
Soon after the gas pipe exploded, the fire brigade started spraying water into the air to [tex]\text{knock down}[/tex] the cloud of the gases in the air but there was not sufficient amount of water in the water sprays and so it was not effective.
Thus the correct answer is option (d).
Define a class Person that represents a person. People have a name, an age, and a phone number. Since people always have a name and an age, your class should have a constructor that has those as parameters.
Answer:
public class Person {
String name;
int age;
String phoneNumber;
public Person(String name, int age, String phoneNumber){
this.name = name;
this.age = age;
this.phoneNumber = phoneNumber;
}
}
Explanation:
The code above is written in Java.
The following should be noted;
(i) To define a class, we begin with the keywords:
public class
This is then followed by the name of the class. In this case, the name is Person. Therefore, we have.
public class Person
(ii) The content of the class definition is contained within the block specified by the curly bracket.
(iii) The class contains instance variables name, age and phoneNumber which are properties specified by the Person class.
The name and phoneNumber are of type String. The age is of type int. We therefore have;
String name;
int age;
String phoneNumber;
(iv) A constructor which initializes the instance variables is also added. The constructor takes in three parameters which are used to respectively initialize the instance variables name, age and phoneNumber.
We therefore have;
public Person(String name, int age, String phoneNumber){
this.name = name;
this.age = age;
this.phoneNumber = phoneNumber;
}
(v) Notice also that a constructor has the same name as the name of the class. In this case, the constructor's name is Person.
Answer:
The class and constructor in C++ is as follows:
class Person {
public:
string name; int age; int phone;
Person (string x, int y) {
name = x; age = y;
}
};
Explanation:
This defines the class
class Person {
The specifies the access specifier
public:
This declares the attributes; name, age and phone number
string name; int age; int phone;
This defines the constructor for the name and age
Person (string x, int y) {
This gets the name and age into the constructor
name = x; age = y;
}
};
interpret the following SQL create table persons (person I'd int, last name varchar (255) first name varchar (255) address varchar (255) city varchar (255)
Answer:
Kindly check explanation
Explanation:
The SQL statement above could be interpreted as follows :
create table command is used to create a table named 'persons' with five columns which are labeled :
person I'd : whose data type is an integer
last name column with a variable character data type with maximum length of 255
first name column with a variable character data type with maximum length of 255
address column with a variable character data type with maximum length of 255
city column with a variable character data type with maximum length of 255
The VARCHAR data type is ideal since we expect the column values to be of variable length.

How is an API different from a web application?
Answer:
Web services (web application) are an API type to be accessed via a network connection. While APIs are application interfaces, this means standardized communication between one application and another application.
Explanation:
Web service is used for communication with REST, SOAP, and XML-RPC.While API for all communication styles is used.
The APIs are all web services. Whereas web services are not APIs.The Web application has no lightweight design, needs a SOAP agreement for sending or receiving system information. While the architecture is lightweight, API is useful for gadgets with limited transmission capacities like smartphones.The web application supports the HTTP protocol only. Whereas the API HTTP/s protocol supports: URL Request / Answer Header etc.The web application is not open source, but any customer who contains XML can devour it. While API is open-source and has a .net framework.is a collection of information stored under a single name

This initializes the product to 1
prod = 1
..... and sum to 0
isum = 0
The following iteration is repeated 4 times
for i in range(4):
Get input for each number
num = float(input())
Calculate the product
prod*=num
Add up the numbers
isum+=num
This calculates the average
avg = isum/4
Print the products
print('{:.0f}'.format(prod))
Print the average
print('{:.3f}'.format(avg))

Alex, a web designer, is assigned the task of creating a mobile device-friendly website for a leading fashion outlet called AllStyles. A desktop version of AllStyles's website already exists. Alex can refer to this desktop version of the website to create the mobile website design The desktop version of the website contains a long list of hyperlinks and this can obstruct the view of the main content when Viewed from a mobile device. Which of the following should Alex use to hide this long list of hypertext links so that it appears only in response to a tap of a major heading in the navigation list?
a. Navigator menus
b. Pulldown menus
c. Pop-up links
d. Header links
Answer: Pulldown menus
Explanation:
Pulldown menus refer to the graphical control element, that is identical to a list box, which enables user to be bake to select one value from a list.
They're regarded as the menu of options that will appear when an item is selected with a mouse. In this case, the item that the user selected will show at the top of the display screen, while the menu appears will show below it.
Therefore, Alex should use the pulldown menus to hide the long list of hypertext links so that it appears only in response to a tap of a major heading in the navigation list.

Prime numbers can be generated by an algorithm known as the Sieve of Eratosthenes. The algorithm for this procedure is presented here. Write a program called primes.js that implements this algorithm. Have the program find and display all the prime numbers up to n = 150.
Sieve of Eratosthenes Algorithm
To Display All Prime Numbers Between 1 and n
Step 1: We need to start with all the numbers representing the range of numbers that are possible candidate primes. So, create an array of consecutive integers from 2 to n: (2,3,4,..n). I wouldn't hand-code this. I would use a loop to populate the array.
Step 2: At each step we select the smallest number and remove all it's multiples. So we'll start with an outer loop that goes from 2 to n. initially, let p equal 2, the first prime number.
Step 3: In an inner loop we need to iterate over all the numbers that are multiples of p, i.e for 2, that's 2,4,6,8 etc. Each time, setting it's value to false in the original array.
Step 4: Find the first number greater than p in the list that is not marked False. If there was no such number, stop. Otherwise, let p now equal this number( which is the next prime), and repeat from step 3.
When the algorithm terminates, all the numbers in the list that are not marked False are prime
Example: Let us take an example when n = 50. So we need to print all print numbers smaller than or equal to 50. We create list of all numbers from 2 to 50.
2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
31 32 33 34 35 36 37 38 39 40
41 42 43 44 45 46 47 48 49 50
Answer:
const MAXNR=150;
let candidates = {};
for(let i=2; i<=MAXNR; i++) {
candidates[i] = true;
}
for(let p=2; p <= MAXNR; p++) {
if (candidates[p]) {
process.stdout.write(`${p} `);
// Now flag all multiples of p as false
i=2;
while(p*i <= MAXNR) {
candidates[p*i] = false;
i++;
}
}
}
