“Programs should always have the form of paragraphs of comments that describe the intention of the program followed by paragraphs of code that implement that intention. All of the formatting should be designed to make readers as able as possible to read the code easily; the compiler doesn’t care. In particular, follow conventions of mathematics and your native language, not those you found in some random language manual. Write the comments first and then write the code, not the other way around. If you don’t know what you want to achieve and why, any code you write is, by definition, incorrect.”
