I am writing a program that is supposed to calculate how much a person earns in a month if the salary is one penny for the first day, two pennies for the second day, four pennies for the third day, and so on with the daily pay doubling each day the employee works. The program should ask the user for the number of days the employee worked during the month and should display a table showing how much the salary was for each day worked, as well as the total pay earned for the month. Here is the code i have so far:
Can someone help me figure out what i am doing wrong?
#include <iostream>
using namespace std;
int main()
{
//Declare variables
int days;
int input;
int cents = 1;
int total =0;
cout<<"\nenter number of days worked: ";
cin>>input;
cin.get();
for(int x = 0; x < input; x++)
{
days = cents;
total += days;
cents *= 2;
}
cout<<"\ntotal pay is :"<<total<<" cents";
for(double x = 0; x < input; x++)
{
cout << "\nday"<<x+1<<" = "<<days<<" cents";
}
system("pause");
return 0;
}Can someone help me figure out what i am doing wrong?

If you need any doubles, they would be cents and total. You only need one loop, with an integer index counting the days. Take another stab at it and think it through step by step.

Working it out on paper will give you a better idea of how to do it. Your input is the number of days, you have a variable called days, so read the input into that variable. Having a variable called input is too vague. Does the number of days change? No. The day may change, but the number of days doesn't. Decide what each variable represents and name it accordingly.
Why would days be equal to cents?
Again, input is not a good name. Replace it with days, or better yet, numDays. cents is a better variable name than input, as is total, but I think you should use variable names like:
One, it is much easier to follow, and two, I think using those variable names will make it much easier to figure out where everything goes.
for(int x = 0; x < input; x++)
{
days = cents;
total += days;
cents *= 2;
}
cout<<"\ntotal pay is :"<<total<<" cents";Why would days be equal to cents?
