EXAMPLE C PROGRAM TO FIND SIMPLE AND COMPOUND INTEREST

#include<stdio.h>
 
#include<math.h>
 
int main()
 
{
 
        int p,t;
 
        float r,si,amount,ci;
 
        printf("Please enter principal,time and rate of interest");
 
        scanf("%d%d%f",&p,&t,&r);
 
        si=p*t*r/100;
 
//Simple Interest formula is p*t*r
 
        printf("\nSimple interest = %.3f",si);
 
//Compound Interest formula is below
 
        amount=p*pow((1 +r/100),t);
 
        ci=amount-p;
 
        printf("\nCompound interest = %.3f",ci);
 
}
