Welcome to lapmos.com

Today we write a program of factorial program using function in c programming language.

So Now let's start the code..

``````#include<stdio.h>

int factorial(int n){
int fact = 1;
for(int i=1; i<=n; i++){
fact = fact * i;
}
return fact;
}

int main()
{
int n;
printf("Enter the number : ");
scanf("%d", &n);

int fact = factorial(n);

printf("The factorial of %d is %d", n, fact);
return 0;
}
``````

Output :

Enter the number : 6
The factorial of 6 is 720

Using recursive function

``````#include<stdio.h>

int factorial(int n){
if(n==0){
return 1;
}
return n * factorial(n-1);
}

int main()
{
int n;
printf("Enter the number : ");
scanf("%d", &n);

int fact = factorial(n);

printf("The factorial of %d is %d", n, fact);
return 0;
}
``````

Output :

Enter the number : 6
The factorial of 6 is 720
