What is Compound interest? Click here to read about it.
Simple interest Formula : ( P x N x R )/100
Compound interest Formula : P ( 1 + R / 100)^N
Where
P : The principal amount.
N : Number of years.
R : Rate of interest.

Code :

#include <stdio.h>
#include <conio.h>
#include <math.h>
void main()
{
        float p,si,ci,r;
        int n;
        clrscr();
        printf("Program to find Interest");
        printf("\n\nPrinciple amount :");
        scanf("%f",&p);
        printf("\nNumber of years :");
        scanf("%d",&n);
        printf("\nRate of interest:");
        scanf("%f",&r);
        si=p*n*r/100; //Simple interest calculation
        printf("\nSimple Interest = %1.2f",si);
        ci=p*pow(1+r/100,n); //Compound interest calculation
        printf("\nCompound Interest = %1.2f",ci);
        getch();
}

Output :

Program to find Interest

Principle amount :5000

Number of years :10

Rate of interest:7.5

Simple Interest = 3750.00
Compound Interest = 10305.16
