Statements will be executed in the order they're written.
Selection structures
Single-selection structure
The if structure is a single-selection
structure because it selects or ignores a single action.
Double-selection structure
The if/else structure is called
a double-selection structure, because it selects between two different
actions.
Multiple-selection structure
The switch structure is called a
multiple-selection structure, because it selects one of many possible
actions. (to be discussed later)
Repetition structures
The while loop has a condition that
is tested before the loop is entered. The loop will continue to execute as
long as that condition is true.
The do/while loop always executes once,
since the condition is given at the end of the loop. The loop will execute
again if the condition is true. (to be discussed later)
The for loop executes a specified number
of times. (to be discussed later)
