Code construction is generally based on c-libraries, class libraries(MFC, etc), p-code systems, interpreted languages(Java), and scripted languages(python, javascript, batch, etc). Linux distributions consist of a variety of code bases and may require various compilers and interpreters to run or compile the code distributions. Most of all this is hidden from you as the packages come with the scripts to cause the compilations and processing to be done without any effort on your part.

Even if you never "plan" to write any code yourself, you may end up writing some simple scripts. These considerations may be something to keep in mind when you choose a Linux distribution for use.
