Write a program to find factorial of a number using recursion

#include<stdio.h>

int factorial(int n);

int main()

{

    int n;

    printf("Enter a positive integer: ");

    scanf("%d",&n);

    printf("Factorial of %d = %ld", n, factorial(n));

    return 0;

}

int factorial(int n)

{

    if(n!=1)

    return n*factorial(n-1);

}
