From Wikipedia, the free encyclopedia. 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.
