Separation and compilation of C + + class templatesIn the past, many class templates were the whole class, along with the implementation, in a header file, such as the STL Library, which implements the class template by following such a strategy.

In the C and C + + languages, an identifier is allowed to represent a string, called a macro, which can be a constant, an expression, a format string, and so on. When compiling preprocessing, all occurrences of the "macro name" in the program are
