int [NUM_TURNS]; 对于define定义的类似函数的宏,最好用内联函数替代,内联函数为前置inline 的函数声明和定义在一起的短小函数。内联函数提供类型检查,同样免除了若干系统调用的过程,得到较高的效率!
是预编译器上符号表的简单替换,不能进行参数有效性检测及使用C++类的成员访问控制。 inline 推出的目的,也正是为了取代这种表达式形式的宏定义,它消除了它的缺点,同时又很好地继承了它的 优点。inline代码放入预编译器符号表中,高效;它是个真正的函数,调用时有严格的参数检测;它也可作为 类的成员函数。 2) 具体...
If you want to use a function across multiple source files, you should declare the function in one header file (.h) and then put the function definition in one source file (.c or .cpp). All code that uses the function should include just the .h file, and you should link the resulti...
Is it because when you put the definition in a header file and include that file in numerous other files, the function is defined many times? I'm also wondering why defining inline functions in header files is okay? I assume that it has something to do with the way the computer manages...
