Simple Programs in C

Let us now write down our second C program.It would simply calculate simple interest for a set of values representing principle,number of years and interest.

/*Calculating of simple interest*/

#include<stdio.h>

#include<conio.h>
int main()

{

int p,n;

float r,si;

p=1000;

n=3;

r=8.5;

/*formula for simple interest*/

si=p*n*r/100;

printf("%f\n",si);

return 0;

}
