VC++6 error C2059: syntax error : 'constant'

Question

Made this simple class with MSVC++ 6.0

class Strg
{
public:
    Strg(int max);
private:
    int _max;
};


Strg::Strg(int max)
{
  _max=max;
}

Sounds good if I use it in :

main()
{
  Strg mvar(10);
}

But Now If I use it in an another class :

class ok
{
public:
    Strg v(45);
};

I get message error : error C2059: syntax error : 'constant'

Could you tell me more please ?

Answer 1

Should be:

class ok
{
public:
    Strg v;
    ok() : v(45) {}
};

Non-static member variables that don't have default constructors (v in this case) should be initialized using initialization lists. In functions (like main) on the other hand you can use the regular constructor syntax.
