The sequence of statements within a compound statement.
- boolean expression

One of the alternative sequences of statements in a conditional statement.
- chained conditional

Where we construct a logical expression with additional comparisons to take advantage of the short-circuit behavior.

- infinite loop
A loop in which the terminating condition is never satisfied or for which there is no terminating condition.
Repeated execution of a set of statements using either a function that calls itself or a loop.
