Q. Factorial of a no. ?

THE OUTPUT WOULD BE

 
#include<stdio.h>
#include<conio.h>
  void main( )
  {       clrscr( );
           int f=1,i,n;
           printf("Enter a number : ");
           scanf("%d",&n);
           for(i=1;i<=n;i++)
           f=f*i;
           printf("Factorial=%d",f);
           getch( );
  }
