C Program to find Factorial with and without using Recursion Function

Coding:


#include<stdio.h>
#include<conio.h>

long fact(long);
void main()
{
int i;long f;

/* Initialization for Factorial without using Recursion
int i,n;
long f=1;   */

clrscr();
printf("\nEnter the number: ");
scanf("%d",&i);
f=fact(i);

/* Factorial without using Recursion
for(n=1;n<=i;n++)
f*=n;  */

printf("\nFactorial of %d is %ld",i,f);
getch();
}

long fact(long k)
{
if(k==0)
return 1;
else
return k*(fact(k-1));

}

Output:
