Write a program that calculates how much a person earns in a month if the salary is one penny the first day and doubles each day worked. The program should ask the user for the number of days 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.

Input validation: Do not accept a number less than 1 or more than 31.

Here is my code so far as I am stumped on how to get the salary to double with each day. I believe you have to set something to =0*2 but not sure exactly what

The stuff in bold I have so far in the above description.

[CODE]

C++ Syntax (Toggle Plain Text)

#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
 
int main ()
{
	int days;
	double	salary;
	double const dailyPay=0.01;
 
 
		cout << "How many days did you work?: ";
		cin >> days;
			while (days <1 || days>31)
				 {cout << "That is an invalid days selection, please select 1-31: ";
				  cin >> days;}
				salary = (dailyPay * 2) * days;
 
 
				cout << "\nPer day                Total";
				cout << "\n-----------------------------\n";
 
				cout << "Your total salary is: " << fixed << setprecision (2) << salary;
			cout << "\n";
 
 
 
return 0;
 
}

#include <iostream> #include <string> #include <iomanip> using namespace std; int main () { int days; double salary; double const dailyPay=0.01; cout << "How many days did you work?: "; cin >> days; while (days <1 || days>31) {cout << "That is an invalid days selection, please select 1-31: "; cin >> days;} salary = (dailyPay * 2) * days; cout << "\nPer day Total"; cout << "\n-----------------------------\n"; cout << "Your total salary is: " << fixed << setprecision (2) << salary; cout << "\n"; return 0; }

Initialize the salary at 1 and, each time through some look that runs 'days' times, double it.

Or you could just use 1 << (n - 1) to compute the amount paid on the nth day, or (1 << n) - 1 will give you the cumulative amount paid after n days.

Line 10. Why is dailyPay a constant? If dailyPay doubles each day, then it is changing and therefore should not be a constant. If you want to have a constant variable, create a variable called firstDayPay , make it constant, assign it to equal one penny, than assign dailyPay to firstDayPay . Then start doubling dailyPay . dailyPay needs to change each day.

What do you mean assign dailyPay to firstDayPay. Do you mean dailyPay=firstDayPay?

Thanks to both of you

Yes. I left out a word: "assign dailyPay to equal firstDayPay"

How about you go through your code by hand with some sample inputs and follow what it is doing. Then you'll see why your code doesn't work.
