type qualifier 类型限制

In the C, C++, and D programming languages, a type qualifier is a keyword that is applied to a type, resulting in a qualified type.
For example, const int is a qualified type representing a constant integer, while int is the corresponding unqualified type, simply an integer.
In D these are known as type constructors, by analogy with constructors in object-oriented programming.

As of 2014 and C11, there are four type qualifiers in standard C:
const (C89), volatile (C89), restrict (C99) and _Atomic (C11)
