C program to find Factorial of a given number using recursive and non recursive functions

/* C program to find the factorial of a given number using non recursive functions */

int factorial(int);

{
   int n,result;
   printf("\n enter any number");
   scanf("%d",&n);
   result=factorial(n);

OUTPUT:
     Enter any number
      4
     factorial of given number 4 is 12
