Need Help solving this. No Clue

Suppose you start with 100 dollars in your account and every year it becomes 1.04 times what you had last year (because there is 4% interest). Write a program that tells you how much money you will have in your account for each of the next 25 years.

Here you go, very easy:

//
//The program to evaluate simple interest
//

#include <cstdio>
#include <cstdlib>
#include <iostream>
#include <string>

using namespace std;

int main(int nNumberofArgs, char* pszArgs[])
{
    double total;
    //Enter the factor
    double principle;
    cout << "Enter the amount of money that is in the bank:" << endl;
    cin >> principle;

    //Enter the principle
    double time;
    cout << "Enter the amount of time your money is in the bank (Months):" << endl;
    cin >> time;
    time = time / 12;

    //enter the rate
    double rate;
    cout << "Enter the interest rate:" << endl;
    cin >> rate;

    //the math for monthly interest
    cout << "Starting month: $" << principle << endl;
    int row = 1;
    double principle2 = principle;
    for(int time1 = 1;time1 <= time;time1++)
    {
        double pre_total;
        pre_total = principle2 * rate;
        principle2 = principle2 + pre_total;
        total = principle2;
        cout << "Year " << row << " - $" << total << endl;
        row++;
    }

    double intgained = principle2 - principle;

    //show results
    cout << "Here is interest gained: $" << intgained << endl;
    cout << "Here is your accumulated money after " << time << " years: $" << total << endl;


    //wait before terminating
    system ("PAUSE");
    return 0;
}
