Source Code Formatting and Names

In professional software development, rigid style guides are normally provided that programmers must adhere to. However, there is no generally accepted good style--readability is the most important requirement, and several different styles are used. The textbook's guide on page 744 will do. For variable and function names, I personally prefer capitalization of each word except the first one (printEmployeeSalary()) rather than the style used in the textbook (print_employee_salary()). As long as your are consistent, either is fine. One rule is important: variable names must be meaningful words, single letter variable names are (almost) never acceptable!
