C Program to Find Simple Interest

#include<stdio.h>
int main()
{
    float principal, rate, time, SI;

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

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

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

    /* Calculate simple interest */
    SI = (principal * rate * time)/100;

    printf("Simple Interest = %f",SI);

    return 0;
}

Output

Enter principle (amount): 1000
Enter Rate: 5
Enter Time in Year: 2
Simple Interest = 100.000000
