Explanation historical development of computer
Answer:
Brief History Of Computer. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. ... Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built.
Explanation:
Computers and electronics play an enormous role in today's society, impacting everything from communication and medicine to science.
Although computers are typically viewed as a modern invention involving electronics, computing predates the use of electrical devices. The ancient abacus was perhaps the first digital computing device. Analog computing dates back several millennia as primitive computing devices were used as early as the ancient Greeks and Romans, the most known complex of which being the Antikythera mechanism. Later devices such as the castle clock (1206), slide rule (c. 1624) and Babbage's Difference Engine (1822) are other examples of early mechanical analog computers.
The introduction of electric power in the 19th century led to the rise of electrical and hybrid electro-mechanical devices to carry out both digital (Hollerith punch-card machine) and analog (Bush’s differential analyzer) calculation. Telephone switching came to be based on this technology, which led to the development of machines that we would recognize as early computers.
The presentation of the Edison Effect in 1885 provided the theoretical background for electronic devices. Originally in the form of vacuum tubes, electronic components were rapidly integrated into electric devices, revolutionizing radio and later television. It was in computers however, where the full impact of electronics was felt. Analog computers used to calculate ballistics were crucial to the outcome of World War II, and the Colossus and the ENIAC, the two earliest electronic digital computers, were developed during the war.
With the invention of solid-state electronics, the transistor and ultimately the integrated circuit, computers would become much smaller and eventually affordable for the average consumer. Today “computers” are present in nearly every aspect of everyday life, from watches to automobiles.
The history of computers is one that began far back 2000 years ago in the city of Babylonia where there was the use of abacus and it has grown to now the use of digital computer as it start in 1642.
What is the history of computer?The history of computers is one that is more than 200 years but in the 19th century, there was the invention of mechanical calculating machines.
Note that the The 1st generation of computers was said to have existed from the year 1940 to 1955 and now it has grown to a whole new level.

Define a class named Money that stores a monetary amount. The class should have two private integer variables, one to store the number of dollars and another to store the number of cents. Add accessor and mutator functions to read and set both member variables. Add another function that returns the monetary amount as a double. Write a program that tests all of your functions with at least two different Money objects.
Answer:
#include<iostream>
using namespace std;
class Money{
private:
int dollars;
int cents;
public:
Money(int d=0, int c=0){
setDollar(d);
setCent(c);
}
void setDollar(int d){
dollars = d;
}
void setCent(int c){
cents = c
}
int getDollar() {
return dollars;
}
int getCent() {
return cents;
}
double getMoney(){
return (dollars + (cents/100));
}
};
// testing the program.
int main(){
Money Acc1(3,50);
cout << M.getMoney() << endl;
Money Acc2;
Acc2.setDollars(20);
Acc2.setCents(30);
cout <<"$" << Acc2.getDollars() << "." << Acc2.getCents() << endl;
return 0;
}
Explanation:
The C++ source code defines the Money class and its methods, the class is used in the main function as a test to create the instances of the money class Acc1 and Acc2.
The object Acc2 is mutated and displayed with the "setDollar and setCent" and "getDollar and getCent" methods respectively.

3.Keyboard
Explanation:
1. A computer mouse (plural mice, rarely mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer.
2.Graphic tablets, because of their stylus-based interface and ability to detect some or all of pressure, tilt, and other attributes of the stylus and its interaction with the tablet, are widely considered to offer a very natural way to create computer graphics, especially two-dimensional computer graphics
3.A keyboard is for putting information including letters, words and numbers into your computer. You press the individual buttons on the keyboard when you type. The number keys across the top of the keyboard are also found on the right of the keyboard. The letter keys are in the centre of the keyboard.

An Olympic-size swimming pool is used in the Olympic Games, where the race course is 50 meters (164.0 ft) in length. "In swimming a lap is the same as a length. By definition, a lap means a complete trip around a race track, in swimming, the pool is the race track. Therefore if you swim from one end to the other, you’ve completed the track and thus you’ve completed one lap or one length." (Source: What Is A Lap In Swimming? Lap Vs Length)
Write the function meters_to_laps() that takes a number of meters as an argument and returns the number of laps. Complete the program to output the number of laps.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
150
the output is:
3.00
Ex: If the input is:
80
the output is:
1.60
Your program must define and call the following function:
def meters_to_laps (length)
Answer:
In Python:
def meters_to_laps(length):
lap = length/50
print('{:.2f}'.format(lap))
Explanation:
This line defines the function
def meters_to_laps(length):
This calculates the number of laps
lap = length/50
This prints the calculated number of laps
print('{:.2f}'.format(lap))
To call the function from main, use:
meters_to_laps(150)
Here is the problem specification: An Internet service provider has three different subscription packages for its customers: Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour. Package B: For $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour. Package C: For $19.95 per month unlimited access is provided. Write a program that calculates a customer's monthly bill. It should ask which package the customer has purchased and how many hours were used. It should then display the total amount due. Input Validation: Be sure the user only selects package A, B or C. Also, the number of hours used in a month cannot exceed 744. Use switch.
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
int hour; char pkg; float bill = 0;
cout<<"Package: "; cin>>pkg;
cout<<"Hour: "; cin>>hour;
if(hour<=744 && hour >=0){
switch (pkg) {
case 'A':
bill = hour * 9.95;
if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}
break;
case 'B':
bill = hour * 14.5;
if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}
break;
case 'C':
bill = 19.95;
break;
default:
cout << "Package must be A, B or C";}
cout<<"Total Bills: $"<<bill; }
else{ cout<<"Hour must be 0 - 744"; }
return 0;
}
Explanation:
This declares all variables: int hour; char pkg; float bill=0;
This prompts the user for package type: cout<<"Package: "; cin>>pkg;
This prompts the user for number of hours: cout<<"Hour: "; cin>>hour;
This checks if hour is between 0 and 744 (inclusive)
if(hour<=744 && hour >=0){
If true, the following is executed
A switch statement to check valid input for package
switch (pkg) {
For 'A' package
case 'A':
Calculate the bill
bill = hour * 9.95;
if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}
End of A package: break;
For 'B' package
case 'B':
Calculate the bill
bill = hour * 14.5;
if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}
End of B package: break;
For C package
case 'C':
Calculate bill: bill = 19.95;
End of C package: break;
If package is not A, or B or C
default:
Prompt the user for valid package cout << "Package must be A, B or C";}
Print total bills: cout<<"Total Bills: $"<<bill; }
If hour is not 0 to 744: else{ cout<<"Hour must be 0 - 744"; }
