Write code for a 3rd Grade math tutor program that provides simple addition questions. Use only numbers in the range 0 to 100 inclusive in the math problems. No number should exceed 100 in the questions or answers.
Answer:
Here is the JAVA program:
import java.util.Random; //to generate random numbers
import java.util.Scanner; //to accept input from user
public class Main { //class name
public static void main(String[] args) { //start of main method
int score = 0; //to store the number of correct answers
Random rand = new Random(); //generates random numbers
int answer; //to store the answers given by student
do { //to keep asking addition questions
int number1 = rand.nextInt(101); //generate random number from 0 to 100 for operand 1
int number2 = rand.nextInt(101); //generate random number from 0 to 100 for operand 2
Scanner input = new Scanner(System.in); //to read input from user
System.out.print("What is " + number1 + " + " + number2 + " ? "); //asks addition question
answer = input.nextInt(); //reads the answer from user(student)
if ((number1 + number2) == answer) //if user answer of addition of two numbers is correct
score = score + 1; //adds 1 to the score each time the answer to the addition question is correct
}while(answer<=100); //keeps asking question until the answer number exceeds 100
System.out.println("Total score is: " + score); }}//displays the total score of student
Explanation:
The above program basically asks addition questions from user. Each addition question has two random numbers and the answer is given by user. At each right answer, the variable score is incremented by 1 in order to store the number of correct answers by user. If the answer to any addition question exceeds 100 then the loop breaks and program stops and the questions answered before that question is considered only.
Another way to do this is to ask 10 addition questions by using random numbers as operands and only that answer is considered which does not exceed 100. Next the if condition checks if the answer to the addition is correct. If this condition evaluates to true then the if condition inside this if condition checks that the value of answer does not exceed 100. If this inner if condition evaluate to true only then the score is incremented to 1 otherwise not and the program displays a message. Here is that program:
import java.util.Random;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
int score = 0;
Random rand = new Random();
for (int i = 0; i < 11; i++) {
int number1 = rand.nextInt(101);
int number2 = rand.nextInt(101);
Scanner input = new Scanner(System.in);
System.out.print("What is " + number1 + " + " + number2 + " ? ");
int answer = input.nextInt();
if ((number1 + number2) == answer)
{ if (answer<=100)
{ score = score + 1;}
else
{System.out.print("Answer should not be greater than 100 \n");} } }
System.out.println("Total score is: " + score); }}
The screenshot of both program outputs is attached.

1. How do you identify the location of components and replacement procedures for notebook systems?
2. How can you tell if a failed notebook display is caused by the screen or the video card?
3. How can you continue to use a notebook if a built-in component (such as a keyboard, pointing device, or network card) fails?
4. When purchasing a replacement internal drive for a notebook, which specifications should you verify before the purchase?
5. What type of notebook internal components may require you to remove the keyboard before replacing that component?
6. How do you fix common problems with a notebook touchpad?
Answer:
1. Best way is to get the manual from the manufacturer. Each manufacturer places the laptop components in different locations and have different methods of securing the components. Dell does a great job in publishing a manual for repair of each component with detailed locations and step-by-step instructions.
2.. You can use an external monitor to test this - assuming the laptop has a external connection (HDMI, DisplayPort, VGA). If the external monitor works, you know the laptop's monitor is the problem. If the external monitor does not work it is likely the display adapter.
3. Failed internal input components can be substituted using external devices. The laptop will have USB connections that can be used for mice, keyboards, network cards, sound cards, and monitors.
4. The main thing to ensure for compatibility is the I/O bus type. SATA / ATA / IDE (older) must be matched to ensure the new drive will work. Look on the label of the old drive to see the specifications. Most modern laptops will user SATA as the I/O connection - both solid state drives and traditional platter based. As long as the I/O bus connection works, you can modify the speed and capacity of the drive with no major issues.
5. It depends on the model, but the majority of the internal components will require removal of the keyboard for access. This includes the system board, video card, network card, sound card, and hard drive. Memory is the one component that the manufacturer will often allow for replacement / addition through an access port on the bottom (but not every manufacturer does this - i.e. Apple)
6. Touchpad problems can be the result of foreign material on the pad (grease, oil, etc), or damage to the pad surface. If cleaning the pad thoroughly or rebooting the computer does not help then you might be looking at a component replacement. Resetting the device drivers can also be attempted.

It’s been six months since the disk crash at CSM Tech Publishing, and the owner is breathing a little easier because you installed a fault-tolerant solution to prevent loss of time and data if a disk crashes in the future. Business is good, and the current solution is starting to run low on disk space. In addition, the owner has some other needs that might require more disk space, and he wants to keep the data on separate volumes (what he calls drives). He wants a flexible solution in which drives and volumes aren’t restricted in their configuration. He also wants to be able to add storage space to existing volumes easily without having to reconfigure existing drives. He has the budget to add a disk storage system that can contain up to 10 HDDs. a. Which Windows feature can accommodate these needs, and how does it work?
Answer:
Storage Spaces
Explanation:
The feature that would best accommodate his needs would be the Storage Spaces feature that has been implemented in the Windows and Windows Server systems. This feature basically takes various hard drives and combines them together, this ultimately acts as copies of each other which protect the data of each one in the unfortunate case that one of the drives tends to fail. This feature also allows you to add more drives to the existing ones with very minimal effort without restricting configuration. Which would solve the needs that are needed in this scenario.

Create a brief program that demonstrates use of a Java exception. For example, you could use InputMismatchException and ask the user to input an integer and show that the program executes correctly if they enter an integer and also show that the exception is thrown and a proper error message is displayed to the user if they input a string of letters. You may want to try it with and without a try catch block for practice, but either one will be sufficient for credit.
Answer:
Here is the program that demonstrates the use of JAVA exception:
import java.util.Scanner; //to accept input from user
public class Main { //class name
public static void main(String[] args) { //start of main method
Scanner input = new java.util.Scanner(System.in); //creates Scanner class object to accept input from user
int number1 = 0; //stores the first integer value
int number2 = 0; //stores the second integer value
while(true) { //keeps looping until user enters integer value
System.out.println("Enter 2 integers to perform addition: "); //prompts user to enter two integer values
try { //defines a chunk of code to check for errors
number1 = input.nextInt(); //reads input integer 1
number2 = input.nextInt(); //reads input integer 2
break; }
catch (java.util.InputMismatchException e) { // defines a code chunk to execute if an error occurs in the try code chunk
System.out.println("Input must be an integer "); //displays this message if user enters anything other than an integer value
input.nextLine(); } } // reads input from user again until user enters both integer type values
System.out.println("The sum is: " + (number1+number2)); } } //if user enters 2 integers then computes and displays the sum of two integer values
Explanation:
The program uses InputMismatchException exception and asks the user to input two integers and computes the sum of two integers if user enters integers otherwise an exception InputMismatchException is thrown and a error message Input must be an integer is displayed to the user if they input a string of letters instead o f integer values. Here while loop is used which keeps executing until user enters both the integer values. After the user enters correct values, the sum of the two integers are computed and result is displayed on output screen. The screenshot of program and its output is attached.
Another program asks the user to input an integer and the program executes correctly if they enter an integer but exception InputMismatchException is thrown with an error message that is is displayed to the user if they input a string of letters. Here is the program:
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new java.util.Scanner(System.in);
int number1 = 0;
while(true) {
System.out.println("Enter an integer value: ");
try {
number1 = input.nextInt();
break; }
catch (java.util.InputMismatchException e) {
System.out.println("Input must be an integer ");
input.nextLine(); } }
System.out.println("The program executed correctly!"); } }

Murray University invested over $450,000 in a customized learning management system so that professors could put courses online and use the Internet to deliver course content and communications to students. After the first year of use, only 20% of the faculty were using the system. Administrators were frustrated to learn that most faculty found the system difficult to use and that students also had difficulty understanding how to find information on the system. This case is an example of which of the following information deficiencies?
a.Lost or bypassed data
b. User-fierce interfaces
c. Data silos
d. Non-standardized data
Answer:
b. User-fierce interfaces
Explanation:
Based on the scenario being described it seems this is an example of User-fierce interfaces. This basically means that the system in question is not very user friendly, which ultimately makes it very difficult for users to understand, use, and manipulate. This tends to cause the users to get frustrated and ultimately stop using the system as they believe it is too difficult and not worth their time. This is what seems to be happening with the customized learning management system in this question since the 20% of the users quit instantly due to the difficulty of the system.
Assuming that the actual process ids of the parent and child process are 2600 and 2650 respectively, what will be printed out at lines A, B, C, D, E, and F? Be sure to explain your answers. int main() { pid_t x, y; int value = 90; value += 30; /* fork a child process */ x = fork(); if (x < 0) { /* error occurred */ fprintf(stderr,"Fork failed"); return(1); } else if (x == 0) { /* child process */ y = getpid(); printf("child: x = %d",x); /* A */ printf("child: y = %d",y); /* B */ value += 20; printf("child: value = %d\n", value); /* C */ exit(0); } else { /* parent process */ y= getpid(); printf("parent: x = %d",x); /* D */ printf("parent: y = %d",y); /* E */ wait(NULL); printf("parent: value = %d\n", value); /* F */ } }
Answer:
Output explanation to the given code can be defined as follows:
Explanation:
In A the output is 0 , It will return fork value of the child process that is 0. so, 0 is printed during child process.
In B the output is 2650 , in which the getpid() method returns the child process id value that is 2650.
In C the output is 140, As it is declared in key, all process have their own "value" copies. 20 are inserted during childhood, so 140 are written.
In D the output is 2650, its fork() method returns the child ID to the parent process. so the value 2650 is printed.
In E the output is 2600, Its getpid() method will returns parent process id that is equal to 2600.
In F the output is 120 Since the value is declared in primary, all process so their own "value" copies. 120 will be printed during process.
A company needs calculating the total working time of employees in a team. You are going to help to write a program that totals the working time in hours and minutes. You should name your program as working_time.py.
Your program should first ask the user how many employees there are on the team. You may assume the value entered will not be negative, but it could be zero. Your program will now be controlled by a loop that asks for, and adds, the hours and minutes for each employee. Of course, the minutes will frequently add up to more than an hour, but you should not report a total time such as 24 hours 77 minutes for example (or worse, 18 hours 377 minutes). Instead you should report the total time as 25 hours 17 minutes. On the other hand, if the total number of hours is 24 or greater you should not report the time in days, hours and minutes. Hours and minutes are all that are to be reported. While you may assume that all of the hours and minutes entered by the user will be nonnegative, a time may be entered with minutes that exceed 60. Your program should be able to handle this and still report the total correctly.
For example, 5 hours, 65 minutes and 3 hours, 88 minutes should add up to 10 hours, 33 minutes. Consequently for a given team we should see output such as:
Total time: 29 hours 18 minutes
Answer:
total_hours = 0
total_minutes = 0
employees = int(input("How many employees there are? "))
for e in range(employees):
hours = int(input("Enter the hours: "))
minutes = int(input("Enter the minutes: "))
total_hours += hours
total_minutes += minutes
if total_minutes >= 60:
total_hours += int(total_minutes / 60)
total_minutes = total_minutes % 60
print("Total time: " + str(total_hours) + " hours " + str(total_minutes) + " minutes")
Explanation:
Initialize the total_hours and total_minutes as 0
Ask the user to enter the number of employees
Create a for loop that iterates for each employee. Inside the loop, ask the user to enter the hours and minutes. Add the hours to total_hours (cumulative sum) and add the minutes to total_minutes (cumulative sum). If the total_minutes is greater than or equal to 60, get the number of hours in the total_minutes, divide total_minutes by 60 and get the integer part. Also, set the total_minutes to remainder of the minutes from 60
When the loop is done, print the hours and minutes as requested
