Lesson 15 - Compilation in C and C++ New

Every program written in C (or C++) must be compiled before running. The basic process of compilation for the C language doesn't differ at all from the compilation for the C++ language, so I'll continue to talk about the C language, but all the information is general and also applies to C++. Because C isn't an interpreted language (such as Java or C#), the program must be compiled directly into binary code that the processor can decode and run directly before running. We'll show you the individual stages of compilation and how you can work with them.

For today's part, we won't work in any IDE, but directly with the command line. The procedure will generally be given for Linux, but can also be run on Windows using Cygwin, which was installed at the beginning of the C series on C programming. Simply find the Cygwin application and run it. The default directory is usually C:/cygwin/home/Ac­countName/ or another location based on where you installed Cygwin. Here we'll insert all the files we'll work with.

author's note: While testing I encountered problems in Cygwin. The solution was to install gcc-g ++: GNU Compiller Collection (C++) into cygwin.
