#include <iostream>
using namespace std; 


void factorial ();


{
	int number = 1; 
	


    cout << "Irasykite skaiciu: ";
	cin >> number;

    if (number < 0)
		cout << "That is not a positive integer.\n";

    else
		cout << number << " Faktorialas yra: " << factorial(number) << endl;




int factorial (int number)

   int y = 1;

     if  (number <= 1)
		 return 1;

	 y = number * factorial(number - 1);
	   return y;
}

here it creates a menu , and in case 'c' it should count a factorial , I added a function , but something is wrong , help please.

btw you shouldn't write stuf in Lithuanian. it would be easyer to understand the program.
