Class variables: public access read-only, but private access read/write

Question

Whoopee, not working on that socket library for the moment. I\'m trying to educate myself a little more in C++.

With classes, is there a way to make a variable read-

Answer 1

A simple solution, like Rob, but without contructor:

class myClass {
    private:
    int m_x=10; // Note: different name than public, read-only interface
    public:
    const int& x=m_x;

};

int main() {
    myClass temp;

    // temp.x is const, so ...
    cout << temp.x << endl; // works
    // temp.x = 57;  // fails

}

Is like a get methode, but shorter. Interesant question ... something like. extent const bool member; can save a lot of getters ...but I don't know languages with this feature...
