9. Write a C program to determine the amount of compound interest to be paid by the borrower, if the principal amount, rate of interest, and tenure are entered by the user.

#include<stdio.h>
#include<math.h>
int main()
{
 float p,rate,time,ci;
 printf("Enter principal amount : ");
 scanf("%f", &p);
 printf("Enter interest rate : ");
 scanf("%f", &rate);
 printf("Enter time period in year : ");
 scanf("%f", &time);
 ci=p*(pow((1+rate/100),time)-1);
 printf("\nCompound interest = %f",ci);
 return 0;
}
