Ans.

/*c program for calculate compound interest*/
#include<stdio.h>
#include<math.h>
#include<conio.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);
 //calculate ci
 ci=p*(pow((1+rate/100),time)-1);
 printf("\nCompound interest = %f",ci);
 return 0;
}

Output :-

Enter principal amount : 48500
Enter interest rate : 6
