1、const/volatile

The const (and volatile) qualifier binds to the left. This means that any time you see const, it is being applied to the token to the left of it. There is one exception, however; if there's nothing to the left of the const, it binds to the right, instead. It's important to remember these rules.

2、explicit

You have a MyString(int size) class with a constructor that constructs a string of the given size. You have a function print(const MyString&), and you call it with print(3). You expect it to print "3", but it prints an empty string of length 3 instead.
