Question

I have a main method in my main.cpp that I would like to display the value of a constant int I have declared.

I added a DeclareConstant class.

Here is my DelcareConstant.h

#pragma once
class DeclareConstant
    {

 public:
     const int x;
     Part1(void);
     Part1(int x);
     ~Part1(void);
     double getX(){return x;}
 };

And source

#include "Part1.h"

Part1::Part1() : x(55){
}

How can I access X so I can display it in my main method? I need to check if I’m even initializing it correctly.

Answer 1

You can access x through getter function getX(), for example:

DeclareConstant dc;
std::cout << dc.getX() << std::endl;

Or

DeclareConstant dc;
std::cout << dc.x << std::endl;

However, you should define your getX like this:

class DeclareConstant
{

 public:
     int getX() const {return x;}

 private:
  const int x; 
 };

And please hide your class member.
