I want to create a little game in c++, and therefore I need a function to return random numbers in a specific range.

Most of the answers I found were similar to this one https://stackoverflow.com/a/19728404/5780938, and I think this is the solution I'm looking for.

To test if the function does, what I want it to, I tried outputting the results in several different ways.

At the moment my code looks like this: 

#include "stdafx.h"
#include <iostream> 
#include <random>


int zufälligeZahl();

int main()
{
using std::cin;
using std::cout;

cout << zufälligeZahl << "\n";
cout << zufälligeZahl << "\n";
cout << zufälligeZahl << "\n";
cout << zufälligeZahl << "\n";

return 0;
}

int zufälligeZahl()
{
std::random_device rd;
std::mt19937 zGenerator(rd());
std::uniform_int_distribution<int> uni(1, 13);

int random_integer = uni(zGenerator); 

return random_integer; 
}

I've tried this in many different ways, but no matter what I do, it doesn't work. Either the output is something like 00A8106E, or I don't get any output at all.

I'm using Visual Studio Community 2015.

You are not calling the function zufälligeZahl, you are printing out the address of the function. Fix your code by actually calling the function: 

 cout << zufälligeZahl() << "\n";

You forgot the parentheses.

  • Oh, damn, that was a stupid mistake :(. The weird thing is, that I actually tried copying solutions from different websites, and it still didn't work. I guess that got me even more confused. Thank you very much for your answer! – Andy Mar 19 '16 at 18:55
