C++ programmers use different programming styles, and so do we: The usual questions about where to put whitespace, delimiters (braces, parentheses), and so forth came up. We tried to be consistent in general, although we occasionally make concessions to the topic at hand. For example, in tutorial sections we may prefer generous use of whitespace and concrete names to help visualize code, whereas in more advanced discussions a more compact style could be more appropriate.

We do want to draw your attention to one slightly uncommon decision regarding the declaration of types, parameters, and variables. Clearly, several styles are possible:
