I have been to use a simple loop to count the number of months it takes to pay off a loan, and it should look like this:

Enter a principal amount:

10000

Enter an annual interest rate:

12

Your first month of interest will be $100.00

Enter the amount of your monthly payment:

200

You borrowed: $10000.00

Your payment schedule consists of 69 payments of $200.00

and a final principal payment of $131.06.

The total amount of interest you pay will be $3931.06.

i have figured out how to do everything except the last three lines. i know how to make math formulas up to calculate it but I am supposed to use a "simple loop" to do it instead. i dont know how to make the loop to figure out the total payments, final principal payments, and total interest.

Here is what i have:

i have been plugging things into the while loop, and have tried numerous for loop combinations but nothing works for me.Code:#include <stdio.h> int main(){ double principal, interest_rate, payment, payments, total_interest; printf("Enter a principal amount:\n"); scanf("%lf", &principal); printf("Enter an annual interest rate:\n"); scanf("%lf", &interest_rate); printf("Your first month of interest will be: %0.2lf\n", (12 / interest_rate * .01) * principal); printf("Enter the amount of your monthly payment:\n"); scanf("%0.2lf", &payment); printf("You borrowed: %0.2lf\n" principal); while( { } }
