Write a program to find the factorial of any number

Write a program to find the factorial of any number.
using function 

1. #include <stdio.h>
2. int fact(int);
3.  
4. void main()
5. {
6.  int num, factorial;
7.  
8.   printf("Please enter any number to find factorial : ");
9.   scanf("%d",&num);
10.   factorial=fact(num);
11.     printf("The number %d factorial is = %d\n",num,factorial);
12.     //printf("Factorial of the number (%d) = %d\n",num,fact(num));
13. }
14.  
15. int fact(int n)
16. {
17.     int i,f=1;
18.     for(i=1;i<=n;i++) {
19.         f=f*i;
20.     }
21.     return f;
22. }

Recursion:

1. #include <stdio.h>
2. 
   
3. int fact(int n)
4. {
5.     if(n==0)
6.         return 1;
7.     else 
8.         return (n*fact(n-1));
9. }
10.  
11. void main()
12. {
13.     int num;
14.     printf("Please enter any number to find factorial : ");
15.     scanf("%d", &num);
16.     printf("The number %d factorial is = %d\n",num,fact(num));
17. }
