Name	Checked	Synopsis
CFL#001		Statements following a case label shall be terminated by a statement that exits the switch statement
CFL#002		All switch statements shall have a default label as the last case label
CFL#003		An else sub-statement of an if statement shall not be an if statement without an else part
CFL#004		Do not use goto
CFL#005		Do not access a modified object more than once in an expression
CFL#006		Do not apply sizeof to an expression with side-effects
CFL#007		Do not change a loop variable inside a for loop block
CFL#008		Always use inclusive lower limits and exclusive upper limits
CFL#009		Never use continue in a nested loop
CFL#010		Never use break to exit a loop
CFL#011		The test condition in control statements shall be a non-assignment expression
CFL#012		Update loop variables close to where the loop condition is specified
CFL#013		All flow control primitives (if, else, while, for, do, switch) shall be followed by a block, even if it is empty
CFL#014		Do not return from unexpected locations
CFL#015		The definition of a void function shall not end with a return statement
CFL#016		Do not have overly complex functions
CFL#017		Do not make explicit comparisons to true or false
CFL#018		Use range-based for loops instead of iterators
CFL#019		Use explicit parentheses when using multiple different operators in an expression
CFL#020		Control should not reach the end of a non-void function without returning a value
CFL#021		Use prefix instead of postfix versions of ++ and -- operators for non-simple types
CFL#022		Apply sizeof to an object rather than to its type
CFL#023		Do not use selection statements (if, switch) instead of a simple assignment or initialization
CFL#024		A statement must have a side-effect, i.e., it must do something.
