1) VC/C++ IDE环境中,可在[Project]|[Settings],C/C++选项卡Category的Code Generation选项的Struct Member Alignment中修改,默认是8字节。VC/C++中的编译选项有/Zp[1|2|4|8|16],/Zpn表示以n字节边界对齐。n字节边界对齐是指一个成员的地址必须安排在成员的尺寸的整数倍地址上或者是n的整数倍地址上,取它们...

传统的编译器通常分为三个部分,前端(frontEnd),优化器(Optimizer)和后端(backEnd). 在编译过程中,前端主要负责词法和语法分析,将源代码转化为抽象语法树;优化器则是在前端的基础上,对得到的中间代码进行优化,使代码更加高效;后端则是将已经优化的中间代码转化为针对各自平台的机器代码。

An additional requirement is that the names of members, including the lack of names for unnamed members, match for structures, unions, and enums, but not necessarily their respective tags. 6.12.3 Single Compilation Compatibility When two declarations in the same scope describe the same object ...
