[C/CPP系列知识] Type difference of character literals 和 bool in C and C++,C/C+中的每一个常亮(everyliteral)都是有类型的,例如10就是int型的
尽管foo()baz中foo()和baz之间没有空格,但因为对foo()做了定义,因此CPP将其作为两个词来处理,中间使用空格分离。 预处理token可以分为这五个大类:identifiers,preprocessing numbers, string literals, punctutators和其它。下面简单介绍这五个类: Identifiers:预处理identifier与C中的identifier是一样的,即:以下划线...
