    Initilization of static const string

    Code:
    FileA.h
    class A{
    public:
      static const int x;
      static const string str;
    ...
    };
    What's the difference to initilize a static const int and a static const string?
    1. Can I initialize static const string str("abc") in the body of class A? Can i do the same for x?
    2. Can I initialize const string str("abc") in the header file but outof class A? how about x?
    3. Shall I use = "abc" instead of ("abc") ?

    Thanks.

    You can initialize a static const int (or any other integral type like char, short, long or bool) inside the class definition if you want.

    Otherwise, you should define the static const variable outside of the class definition and inside a source file. If you did it in a header file you would likely get multiple definition errors.

    You can use = "abc" or ("abc"), either will work.
