Simple interest calculation in C

 #include <stdio.h>

int main() {

    float principal, rate, time, interest;

    // Input principal amount

    printf("Enter principal amount: ");

    scanf("%f", &principal);

    // Input rate of interest

    printf("Enter rate of interest (in percentage): ");

    scanf("%f", &rate);

    // Input time period in years

    printf("Enter time in years: ");

    scanf("%f", &time);

    // Calculate simple interest

    interest = (principal * rate * time) / 100;

    // Display the result

    printf("Simple Interest = %.2f\n", interest);

    return 0;

}
