C program to calculate the Simple interest and Compound interest when Principal, Rate & Time are given.

Program :

#include<stdio.h> // here p=pricipal value,r=rate,t=time

#include<conio.h> // si=simple interest, ci=compound interest

#include<math.h>

void main()

{ float p,r,t,si,ci;

clrscr();

printf("Enter the values of Principal :\n");

scanf("%f",&p);

printf("Enter the value of Rate :\n");

scanf("%f",&r);

printf("Enter the value of Time :\n");

scanf("%f",&t);

si=(p*r*t)/100;

ci=p*(pow((1+r/100),t));

printf("S.I is :%f\n",si);

printf("C.I is :%f",ci);

getch();

}
