Question
C++ Program
A.
Write a program that calculates how much a person would earn over a period of time if his or her salary is one penny the first day and two pennies the second day, and continues to double each day. The program should ask the user for the number of days. Display a table showing how much the salary was for each day, and then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.
Using do while loop.
Explanation / Answer
#include <iostream>
using namespace std;
int main()
{
int n;
int total = 0;
cout << "Enter the number of days: ";
cin >> n;
if(n<1){
cout<<"Invalid input. Input must be greater than 0"<<endl;
}
else{
int i=0;
cout<<"Day Salary"<<endl;
do{
i++;
cout<<i<<" "<<(i * 2)<<endl;
total = total + (i * 2);
}while(i<=n);
cout<<"Total Pay: "<<total<<endl;
}
return 0;
}
Output:
sh-4.2$ g++ -o main *.cpp
sh-4.2$ main
Enter the number of days: 5
Day Salary
1 2
2 4
3 6
4 8
5 10
6 12
Total Pay: 42
