Why does my class return not 0?

[stonedviper]

Hello!
I'm currently studying classes.
And so far I got the hang of it.
But I started to experiment somethings and one of those things is this code

// array of structures
#include <iostream>
#include <string>
#include <sstream>

using namespace std;

class vaas
{
    int niko;
    public:
        vaas()
        {
            niko=0;
        }
};

int main ()
{
    //int a;
    vaas john();
    cout<<john;
    //cout<<vaas.age;
}

my question is why does it output 1 instead of 0?
Thank you for your time and answers :)!

void john();
int john();
std::string john();

those are function declarations, then it is expected that vaas john(); would also be a function declaration.

To create an object using the default constructor write vaas john;, note the lack of parenthesis, or vaas john{};, with curly braces.


Then you'll have a compile error on cout<<john; as you never especified how a `vaas' may be print to screen.
