Write a program to display factorial of a number

   1:  #include<conio.h>

   2:  #include<stdio.h>

   3:  void main()

   4:  {

   5:  int n,i;

   6:  long int fact;

   7:  clrscr();

   8:  printf("Enter the no whose factorial is required\n");

   9:  scanf("%d",&n);

  10:  fact=1;

  11:  i=1;

  12:  if(n>=2)

  13:  while(i<=n)

  14:  {

  15:  fact=fact*i;

  16:  i++;

  17:  }

  18:  printf("Factorial of the %d is %ld\n",n,fact);

  19:  getch();

  20:  }
