The header files in C contain prewritten codes that can be used in multiple programs. There are two primary types- standard library files and user-defined header files. Understanding how to use them is an integ

例如编译器会提醒你"xxx" has already been declared in the xxx file或类似的讯息,就是发生重複编译 这就是标头守卫(header guards)该挺身而出的时候,它的目的就是防止标头档内容被重複编译,例如各种类型的数据、结构体数据、静态变数等等 回到原先的程式范例,我们来改写它: /*test1.h*/ #ifndef __TEST1_H...
