如何查看 Visual C++ 预处理器的输出?
我想在我的代码上看到 Visual C++ 预处理器的输出――即等效于 gcc -E.对于我的生活，我找不到相关的编译器开关.我该如何实现?
I want to see the output of the Visual C++ Preprocessor on my code -- i.e., the equivalent of gcc -E. For the life of me, I cannot find the relevant compiler switch. How do I accomplish this?
推荐答案
cl.exe，Microsoft Visual C++ 的命令行界面，具有三种不同的输出预处理文件的选项(因此不一致在之前关于 Visual C++ 的回复中):
cl.exe, the command line interface to Microsoft Visual C++, has three different options for outputting the preprocessed file (hence the inconsistency in the previous responses about Visual C++):
/E:预处理到标准输出(类似于 GCC 的 -E 选项)/P:预处理到文件/EP:预处理到标准输出，无需#line指令
/E: preprocess to stdout (similar to GCC's -E option)/P: preprocess to file/EP: preprocess to stdout without #line directives
