Control Structures

Any compiler formula is built out of a series of statements. A statement can be an assignment, a function call, a loop, a conditional statement or even a statement that does nothing (an empty statement). Statements usually end with a semicolon. In addition, statements can be grouped into a statement-group by encapsulating a group of statements with curly braces, forming a block. A statement-group is a statement by itself as well. The various statement types are described in this chapter.
