[discuss] inaccurate description

[kingFighter]

Quote
Reference to const
There is no const reference because the reference itself is a const pointer

reference is NOT an object, that's the reason why NO reference itself is const.

// class
class A
{
private:
    const int a;                // constant object member, can only be assigned in the initialization list
};

// constant object member, can only be assigned in the initialization list is not accurate, besides initialization list, we can use in-class initializer since C++11

// class
class A
{
private:
    const int a=1;                // constant object member, can only be assigned in the initialization list
};

It has been modified, thanks

Understand what functions C ++ silently writes and calls (the compiler secretly creates a default constructor, copy constructor, copy assignment operator, destructor for class)
C++11 secretly creates move constructor, move assignment operator , above is true before C++11. Better to put comment about it.
