White Space

White space is your friend. You wouldn’t write a book with no spaces between words, or line breaks between paragraphs, or no chapter divisions, would you? Then why would you write code with no white space? White space allows you to logically separate parts of the program and to line up block separators and other lexical elements. It also lets your eyes rest between parts of the program. Resting your eyes is a good thing. The following are some suggestions on the use of white space:

• Use blank lines to separate groups (just like paragraphs).
• Within a block align all the statements to the same tab stop (the default tab width is normally four spaces).
• Use indentation to show the logical structure of each control structure and block.
