Question

Is it possible to initialize in a class a global const in a class method? I would like to use a method in my class to set the const.

My idea was:

/* a.h */
class A {
private:
    const string cs;

public:
    A();
    ~A();

    bool cs(const string &host, ...)
};

/* a.cpp */
A::A(){
}

A::~A(){
}

bool cs(const string &host, ...) {
    /* check some values */
    cs = "Set Vaule";   //Doesnt work, get an compiler error
}

Is It possible to set a global const in a method?

No. You could initialize it in a constructor initializer, but once initialized a const member cannot be changed. Otherwise, it wouldn’t be a constant, now, would it?
