Turbo C gives Output as 0.000000

I have set the correct directory paths for Turbo C. But yet it gives the output as 0.000000

Following is the program:

#include <conio.h>
#include <math.h>
#include <stdio.h>

void main() {
    int n;
    float r, si, ci, p;
    clrscr();
    printf("enter principle amount\n");
    scanf("%f", &p);
    printf("enter rate of interest\n");
    scanf("%d", &r);
    printf("enter number of years\n");
    scanf("%f", &n);
    si = p * n * r / 100;
    ci = p * (pow((1 + (r / 100)), n) - 1);
    printf("simple interest=%f\n", si);
    printf("compound interest=%f", ci);
    getch();
}

It is supposed to give numbers instead of 0.000000

Any help?

Solution

  • Change:

    scanf("%f",&n);

    to:

    scanf("%d",&n);

    since n is an integer, not a float, as suggested in the comments already.

    For r, which is of type float, you should use scanf("%f",&r);.

    PS: Consider using a modern compiler, such as GCC.
