Write a program to return factorial of a num as a long interger variable

 

   1:  #include<stdio.h>

   2:  #include<conio.h>

   3:  long getfact(int n);

   4:  void main()

   5:  {

   6:  int k;

   7:  long f;

   8:  printf("Enter the num: ");

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

  10:  f=getfact(k);

  11:  printf("Factorial of %d is:%ld\n",k,f);

  12:  getch();

  13:  }

  14:  long getfact(int n)

  15:  {

  16:  long fact=1;

  17:  int i;

  18:  for(i=2;i<=n;i++)

  19:  fact=fact*i;

  20:  return(fact);

  21:  }
