class constructor question

[StGuru]

Here is the code that I worked with:

#include <iostream>

using namespace std;


class test
{
 int c;
 
friend void funkcija(test);

 public:
 
int d;
           test(){ cout<<"Unparametrized constructor."<<endl;}
        
           test(const test &objekat)
               {
                 cout<<"Copy constructor called."<<endl;
                 
               }
 

};

void funkcija(test objekat){


cout<<objekat.c<<endl;
cout<<objekat.d;


}
int main()
{
    test ob;
    
    funkcija(ob);
    
    system("PAUSE");
    
    return 0;
}

The copy constructor is made to make deep copy of the object. So to make sure that the members of the class test (c,d) exist I printed their values in the function (no matter the printed text is non-understandable, I can still change their values (for ex. object.c=5 or object.d=33) so they obviously exist.
