C++ Program To Find A Factorial Of A Number.

/* Declaration Of Header Files */
# include <iostream.h>
# include <conio.h>

/* Start Of Main Program */
void main()

{

   /* Declaration Of Variables */
   int i, Num = 0, f;

   clrscr();

   /* Asking For The Input From User */
   cout << " Enter Any Number : ";

   cin >> Num;

   /* Source Code For Computing Factorial Of A Number */
   f  =  1;

   for ( i  =  Num;  i  >  0;  i-- )

   {

       f  =  f  *  i;

   }

   cout << " Factorial Of  No. " << Num << " : " << f;

   getch();

}
