Write a C program for simple interest calculation

#include<stdio.h>
#include<conio.h>
#include<math.h>
  main()
{
  int p,r,t;
  float x;
  clrscr();
  printf("\n enter the values of p,r and t");
  scanf("\n %d%d%d",&p,&r,&t);
  x=((p*r*t)/100;
  printf("\n x=%f",x);
  return(0);
}

output:-
 enter the value of p=100
 enter the value of r=10
 enter the value of t=2
 x=20.000
