Thread: help with compounded interest

The code below was supposed to display interest yearly like:
Year 1 $1000
Year 2 $1100
Year 3 $1210

Problem is it will display the value for the last year for all 3 years... what am i doing wrong?

Code:

#include <iostream>
#include <cmath>
using namespace std;

int main()
{

//Declare variables
double percent_return = 0;
double investment = 0;
int nYears = 0;
double value = 0;
int count = 0;


//Ask user for initial amount 
cout << "Enter the initial amount of the investment: " << endl;
cin >> investment;

//Ask user for interest rate
cout << "Enter the interest rate: " << endl;
cin >> percent_return;

//Ask user for number of years
cout << "Enter the number of years: " << endl;
cin >> nYears;

for(count = 1; count <= nYears; count++)
{

value = investment * pow(1 + percent_return, nYears);

cout << value << endl;

}



return 0;

}

Code:

value = investment * pow(1 + percent_return, nYears);

The problem is on that line
investment never changes
percent_return never either
neither does nYears
Well, something got to change during the iteration of the loop. What would that be?
Welcome to the board

Code:

value = investment * pow(1 + percent_return, count);
