I need to create a program where the user puts in a an amount of 'will' that their uncle left for them after he passed away. I need to also ask the user how much of the money they are going to use each year, and ask them how much interest their account has. The program should then print out the amount of money after each year considering the added interest and subtracting 'the amount used each year' (which is given by the user) I have completed most of the program...
I just need some help printing everything I need out and making sure my loop is correct.
This is copy of a sample run of what it should look like and below the sample run there is a copy of MY program and how far I have gotten:
Sample Run:
Year Payment Money Left ---- ------- ---------- 1 1500.00 9500.00 2 1500.00 8950.00 3 1500.00 8345.00 4 1500.00 7679.50 5 1500.00 6947.45 6 1500.00 6142.20 7 1500.00 5256.41 8 1500.00 4282.06 9 1500.00 3210.26 10 1500.00 2031.29 11 1500.00 734.42 12 807.86 0.00
This is a copy of my program:
#include <stdio.h>
int main () {
int will, annual_amt_used, rate, counter, balance;
printf("What was the amount of the inheritance?\n"); scanf("%d", &will); printf("What is the the amount you will use each year?\n"); scanf("%d", &annual_amt_used); printf("What is the interest rate on the account?\n"); scanf("%d", &rate);
for (counter=0; counter < NOT SURE WHAT TO PUT HERE ; counter++)
{ balance=(balance * (rate/100))+balance; // balance= (balance * int_rate) +balance; printf("%.2lf\n", balance); }
system("PAUSE"); return 0;
}

You can use while loop instead of for loop like this:
while(balance > 0) { balance=(balance * (rate/100))+balance; // balance= (balance * int_rate) +balance; printf("%.2lf\n", balance); }
