The first step in good programming is to understand fully what the

program is supposed to do and the relationship between the inputs and the outputs.

The second step is to break down the process into its smallest component. This is

called modularity. A flowchart is very useful here. It is because of modularity

that you can use "libraries" of functions so that you don't have to reinvent the

wheel every time you program something.

The third step, implementation, is where you put together all the modules

according to the flowchart you designed.
