What are some concepts people should understand before programming "big" projects?
- by Abafei
A person new to programming may be able to make a good small program.
However, when starting to work on anything bigger than a small (think 1 C source file or Python module) program, there are some general concepts which become much more important when working on "big" (think many Python modules or C files) programs; one example is modularity, another is having a set aim.
Some of these may be obvious to people who went to school to learn programming; however, people like me who did not go to programming classes sometimes have to learn these things from experience, possibly creating failed projects in the meantime.
==================================================
Please explain what the concept is, and why the concept becomes more important for big programs than by small programs.
Please give only 1 concept per answer.
