Write a C Program to Calculate compound interest.

#include<stdio.h> 

void main()

{
    float principle,rate,time,ci;

    printf("Enter principle amount: ");
    scanf("%f", &principle);

    printf("Enter time in years: ");
    scanf("%f", &time);

    printf("Enter rate: ");
    scanf("%f", &rate);

    ci = principle* (pow((1 + rate / 100), time));

    printf("Compound Interest = %f", ci);

    getch();

}
