**Write a C program to calculate compound interest.**

#include <math.h>

int main() {

float principal, rate, amount, CI;

int n;

/*

* get the values for principal,

* rate, period from user

*/

printf("Enter the value for principal:");

scanf("%f", &principal);

printf("Enter the value for rate:");

scanf("%f", &rate);

printf("Enter the value of n:");

scanf("%d", &n);

/* calculate the total amount */

amount = principal * pow((1 + rate/100), n);

/* find the compound interest */

CI = amount - principal;

/* print the result */

printf("Compound Interest is %f\n", CI);

return 0;

}

**Output:**

jp@jp-VirtualBox:~/$ ./a.out

Enter the value for principal:1000

Enter the value for rate:10

Enter the value of n:2

Compound Interest is 210.00

Enter the value for principal:1000

Enter the value for rate:10

Enter the value of n:2

Compound Interest is 210.00

C programming is not a simple computer language, which could be learnt by anyone at any time. Thanks for this program.
