F.9 Overall Program Spacing

• Variable declarations fall immediately beneath the opening curly brace, and should initialize the variable right there whenever initialization is used.
• One line between the last variable declaration and the first line of real code.
• The return statement of a function (when used as the last line of a function) should have one blank line above it and none below it.
• Really long functions (those whose entire body is longer than 24 lines) should have a comment immediately following the closing curly brace of the function, telling you what function the closing brace terminates.
