// C program to find factorial of a number using recursion
#include <stdio.h>

// @recursive function to find the factorial
long int RecursiveFacto(int fact_number) {

// @driver function to call & find
// @factorial of a number using recursion
int main() {
    int fact_number = 0;

    printf("Enter a positive integer number: ");
    scanf("%d", &fact_number);

    // It will call the RecursiveFacto() function
    printf("\nFactorial of %d is: %ld\n", fact_number, RecursiveFacto(fact_number));
    return 0;
