Aim:

To write a ‘C’ program to find the simple interest and Compound interest for the Amount (P), Rate of Interest (R) and Number of years (N)

Algorithm:

1.      Read Principal (P), Rate of Interest (R) and Number of years (N).

2.      Calculate Simple Interest (SI) and Compound Interest using the formula
              SI=(P*N*R)/100
              CI=P * ((1+R)/100)^N –P

3.      Display the result.

4.      Stop

Program:

/* Program to calculate Simple Interest and Compound Interest */

#include<conio.h>

#include<stdio.h>

#include<math.h>               // For pow function

void main()

{

          double p,n,r,si,ci,x;

          clrscr();

          printf("Enter the principal:Rs ");

          scanf("%lf",&p);

          printf("Enter rate of interest:");

          scanf("%lf",&r);

          printf("Enter number of years:");

          scanf("%lf",&n);

/* To calculate Simple Interest*/

          si=p*n*r/100;

/* To calculate Compound Interest*/

          ci=pow((1+r/100),n)*p-p;

/* Display the result*/

          printf("\n\nSimple interest =Rs %.2lf\n\n",si);

          printf("Compound Interest =Rs %.2lf",ci);

          getch();

}

Output:

Enter the principal:Rs 2000

Enter rate of interest:2

Enter number of years:3

Simple interest =Rs 120.00

Compound Interest =Rs 122.42
