C Program to Calculate Compound Interest

Compound interest is computed by multiplying the original principal amount by one plus the annual interest rate multiplied by the number of compound periods multiplied by one. Following that, the total initial loan amount is removed from the resultant value.

Source code:

#include<stdio.h>
#include<math.h>
int main()
{

   double princ, amount;
   float rate, time;
   int n;

   printf("Enter principal amount: ");
   scanf("%lf",&princ);
   printf("Enter rate, time and number of times: ");
   scanf("%f %f %d",&rate, &time, &n);

   // calculating compound interest
   amount = princ*pow( (1+(rate/n)), (n*time));

   // print result
   printf("Amount=%.2lf",amount);

   return 0;
}

Output:

Enter principal amount: 5000
Enter rate, time and number of times: 0.2 5 6
Amount=10234
