Document Summary
Most program of any sized consist of multiple files. To understand how to use objects and functions in multi file programs requires an understanding of storage classes. Its storage class determines an object or function"s scope, duration, and linkage. There are four distinct stages involved in the compilation of a program. When using an ide these stages are carried out seamlessly without your intervention. Translation unit: a source file and all the header files referenced by #include directives. If the compiler finds no errors in the translation unit, it generates and object file (module) containing the machine code. The compiler translates each translation unit of a program into a separate object file. The compiler invokes a the linker, which combines the object file and any necessary library functions into an executable file. The executable file also contains any information that the target operating system needs in order to load and start it.
