1.2.5.3 The block statement

There are a lot of statements, for example conditional statements, that in certain circumstances execute one specified statement and never otherwise. Suppose you want to have several statements executed and not just a single one? Well, there's a special statement called block statement that will allow you to do that. A block is defined as starting with a { and ending with a }. Within that block you may have as many statements of any kind (including variable definitions) as you like. The block statement is not ending with a ;, even though it wouldn't matter if you accidentally put one there.
