Program in C to find factorial of an integer using both recursive and non-recursive functions

Write C programs that use both recursive and non-recursive functions - To find the factorial of a given integer

#include<stdio.h>

#include<conio.h>

unsigned int recr_factorial(int n);

unsigned int iter_factorial(int n);

void main()

{

            int n,i;

            long fact;

            clrscr();

            printf("Enter the number: ");

            scanf("%d",&n);

            if(n==0)

                        printf("Factorial of 0 is 1\n");

            else

            {

                        printf("Factorial of %d Using Recursive Function is %d\n",n,recr_factorial(n));

                        printf("Factorial of %d Using Non-Recursive Function is %d\n",n,iter_factorial(n));

            }

            getch();

}

/* Recursive Function*/

unsigned int recr_factorial(int n) {

            return n>=1 ? n * recr_factorial(n-1) : 1;

}

/* Non-Recursive Function*/

unsigned int iter_factorial(int n) {

            int accu = 1;

            int i;

            for(i = 1; i <= n; i++) {

                        accu *= i;

            }

            return accu;
