Assignment operator - Self-assignment

Question

Does the compiler generated assignment operator guard against self assignment?

class T {

   int x;
public:
   T(int X = 0): x(X) {}
};

int main()
{
   T a(         


        

Answer 1

class T {
    int x;
public:
    T(int X = 0): x(X) {}
// prevent copying
private:
    T& operator=(const T&);
};
