C++ Programming Process
 

All software programs must have internal documentation to identify the vital information about the program like author, name, date, filename, location, limitation of the program and many more. It must have throughout the documentation of source code, which must be consistent and clear. It must include directive in a special instruction for C++ compiler. The compiler includes contents of another file also. All the files, which are included in the software, are the header files. The directive includes merge files of source code from one file to another in a convenient way without retyping the code.
