This raises the question: what happens when you have a declaration with the same name as an identifier in a containing block? If you do that, you shadow the identifier created in the outer block.Shadowing Variables Before I explain what shadowing is, let’s take a look at some code (see...
From the latter (#3 and part of #4): >3 A label name is the only kind of identifier that has function scope. >It can be used (in a goto statement) anywhere in the function in which >it appears, and is declared implicitly by its syntactic appearance >(followed by a : and a st...
