#include<stdio.h>

int factorial(int);

int main()

{

    int n;

    printf("Enter the number:");

    scanf("%d",&n);

    printf("The factorial is %d",factorial(n));

    return 0;

}

int factorial(int n)

{

    if(n<=1)

    {

    return 1;

    }

    else

    {

    return n*factorial(n-1);

    }

}
