Why can't access static file with this pointer?

Question

Example I have a program:

class TestStatic
 {
   private:<br>
    static int staticvariable;

   public:<br>
    TestStatic() {
    this->staticvariable = 0;
    cout << this->staticvariable;
}

~TestStatic() {}
};

int main() {
 TestStatic object;
 return 0;
}

why this pointer can't access staticvariable . I don't understand why.

Probably because staticvariable is not bound to this but to your class. Check out the following answers:

Hope it helps.

thank you for answering, but, i also don't know why. what is type of file this pointer can access – Hồng Phúc Sep 16 '18 at 14:10
ah, ok ,i have just understood, the problem is not this pointer – Hồng Phúc Sep 16 '18 at 14:12
No, the problem is not the pointer. You can access static variables using the name of the class, followed by two colons (`:`). In your case that would be `TestStatic::staticvariable`. – Léopold Houdin Sep 16 '18 at 14:14
