分享134 c语言吧 液晶资料 c语言语句#define name((pointer_type *) reg_name )什么意思 分享3赞 计算机吧 杀杀杀顶顶顶5 求助感觉c++中tydefine没啥用啊上数据结构课用了class来写复数的四则运算,老师直接说不行要我用tydefine定义一个结构体来写,但我感觉两个都可以运行啊,而且我觉得class跟tydefine还没...
(2). 使用宏 PRINT_SOURCE_INFO(),Debug/Release 方式编译输出结果大致相同,均是 MacroTest.cpp 的信息,只是 Debug 输出的 __FILE__ 是全路径,而 Release 输出的是相对路径: File: d:\source\macrotest\macrotest.cpp, Line: 14, Date: Aug 28 2011, Time: 07:42:30, Timestamp: Sun Aug 28 07:3...
to use a pair of parentheses following the macro name. A function-like macro’s name is only prolonged if and only if it is followed by a pair of parentheses. If we don’t do this, the function pointer will be set to the real function’s address, which will result in a syntax ...

When you're using C++\CLI to define types, thethispointer in a reference type is of typehandle. Thethispointer in a value type is of typeinterior pointer. These different semantics of thethispointer can cause unexpected behavior when a default indexer is called. The next example shows the ...

creates the type PFI, for ``pointer to function (of two char * arguments) returning int,'' which can be used in contexts like PFI strcmp, numcmp; in the sort program of Chapter 5. Besides purely aesthetic issues, there are two main reasons for using typedefs. The first is to parameter...
