预处理(或称预编译)是指在进行编译的第一遍扫描(词法扫描和语法分析)之前所作的工作。预处理指令指示在程序正式编译前就由编译器进行的操作,可放在程序中任何位置。 预处理是C语言的一个重要功能,它由预处理程序负责完成。当对一个源文件进行编译时,系统将自动引用预处理程序对源程序中的预处理部分作处理,处理完...
例如,有整型量int a,b。其中int是整型变量的类型说明符。int的完整写法为integer,为增加程序的可读性,可把整型说明符用typedef定义为typedef int INTEGER。此后就可用INTEGER来代替int作整型变量的类型说明,如INTEGER a,b等效于int a,b。 用typedef定义数组、指针、结构等类型将带来很大的方便,不仅使程序书写简单而且...
