We successfully prepared the C++ compiler and you learned how to compile the source code file you created using the compiler. Do not forget to use the -Wall (Warning All) option every time you compile the source code because it is important to avoid a warning and subtle error. Also, it is important to use the -ansi and -pedantic options so that your source code is able to be compiled in any compiler, as it will check the ANSI standard and reject non-ISO programs.

Now, we can go to the next chapter to learn the networking concept so that you can understand network architecture in order to ease your network application programming process.
