Q. Calculate Simple Interest ?

THE OUTPUT WOULD BE

 
#include<stdio.h>
#include<conio.h>
  void main( )
  {    clrscr( );
        float s,p,r,t;
        printf("Enter principle value : ");
        scanf("%f",&p);
        printf("Enter rate : ");
        scanf("%f",&r);
        printf("Enter time : ");
        scanf("%f",&t);
        s=p*r*t/100;
        printf("Simple Interest=%.2f",s);
        getch( );
}
