The exception to this is when the variable is ``const`` in which case the declaration must be at the point of first use/assignment. + Declaring variable inside a for loop is OK. * When declaring variables in functions, multiple variables per line are OK. However, if multiple declarations would cause the line to exceed a reasonable line length, begin a new set of declarations on the next line rather than using a line continuation. * Be careful to not obfuscate the code by initializing variables in the declarations, only the last variable on a line should be initialized. -- 2.34.1
