C program compile and link:
Pretreatment:
1, replacing all the macro definition #define
2, the processing conditional compilation directives like #if #lese #endif
3, the header file is inserted into the expanded position precompiled specified, # include ""
Compiler: a .cpp files generated .obj files
Note: .h file does not participate in the compilation, content .h be included in the text at the time of the pre-treatment

Common mistakes:
1, repeated definition of global variables
