Chapter 5 ■ Programs with Repetition Logic
A solution to this problem is given in Program P5.18.
Program P5.18
#include <stdio.h>
int main() {
int year;
double initialDeposit, interestRate, target, deposit, interest;
printf("Initial deposit? ");
scanf("%lf", &initialDeposit);
printf("Rate of interest? ");
scanf("%lf", &interestRate);
printf("Target deposit? ");
scanf("%lf", &target);
}
printf("\nYear Deposit Interest\n\n");
deposit = initialDeposit;
year = 0;
do {
year++;
interest = deposit * interestRate / 100;
printf("%3d %8.2f %8.2f\n", year, deposit, interest);
deposit += interest;
} while (deposit <= target);
printf("\nDeposit exceeds $%7.2f at the end of year %d\n", target, year);
The program uses the following variables:
initialDeposit
interestRate
target
deposit
1000, in the example
10, in the example
2000, in the example
the deposit at any given time
135
