什么是 C++ 中的标记字符串？
What is a token string in c++?
The #define creates a macro, which is the association of an identifier
or parameterized identifier with a token string. After the macro is
defined, the compiler can substitute the token string for each
occurrence of the identifier in the source file.

令人惊讶的是，这个问题并没有被直接问到，而是询问了 tokenization、tokenizer、tokening 等。甚至在 DuckDuckGo 上搜索，最接近的问题是在 quora 上问，
我不清楚 string token 和 token string 是否同义。所以要明确一点：
C++ 中的标记字符串是什么？
在这种情况下，令牌字符串 是宏体。在
#defined MAKE_MY_FUNC(x) void x(int bar)
void x(int foo) 部分将被视为 令牌字符串 并且当您使用 MAKE_MY_FUNC 时
MAKE_MY_FUNC(foo){ std::cout << bar; }
然后token string将被替换，代码将被转换为
void foo(int foo){ std::cout << bar; }

中给你他们所谓的token-string
The token-string argument consists of a series of tokens, such as keywords, constants, or complete statements. One or more white-space characters must separate token-string from identifier. This white space is not considered part of the substituted text, nor is any white space that follows the last token of the text.
