针对c语言编程中应该注意的问题做的总结，包括了常见的指针问题，编译环境问题，内存溢出问题等等。非常实用，对症下药。避免c语言使用者少走弯路。-C language programming for the problem should be paid attention to do a summary, including a common indicator questions, compile environmental problems, memory overflow problems, and so. Very practical problem directly. Avoid making detours to avoid the c language users.
