Program to find Factorial of a Number

Following is the program to find factorial of a number using for loop.

#include<stdio.h>
#include<conio.h>
void main()
{
   int fact,i,n;
   fact = 1;
   printf("Enter the number\t");
   scanf("%d" , &n);
   for(i = 1; i <= n; i++)
   {
       fact = fact*i;		
   }
   printf("Factorial of %d is %d", n , fact);
   getch();
}

Output

Enter the number 5 
Factorial of 5 is 120

Program to find Factorial of a Number using Recursion

In this program we will not use for loop, but we will find the factorial using recursion.

#include<stdio.h>
#include<conio.h>
int factorial(int n);
void main()
{
   int fact, i, n;
   printf("Enter the number\t");
   scanf("%d", &n);
   fact = factorial(n);
   printf("Factorial of %d is %d", n, fact);
   getch();
}

int factorial(int n)
{
   int fact = 1;
   if(n==1)
   { 
      return fact; 
   }
   else
   {
      fact = n * factorial(n-1);
      return fact;
   }
}

Output

Enter the number 5 
Factorial of 5 is 120
