Exam 2: Functions and Control Structures

The ____________________ statement repeats a statement or series of statements as long as a given conditional expression evaluates to TRUE.

In a(n) ____________________ loop, a loop statement never ends because its conditional expression is never FALSE.

When one decision-making statement is contained within another decision-making statement, they are referred to as multiple decision-making structures.

The switch statement compares the value of an expression to a value contained within a special statement called a ____________________.

A ____ is a variable that increments or decrements with each iteration of a loop statement

What will be returned if you use a local variable outside the function in which it is declared?

Each repetition of a looping statement is called a(n) ____________________.

In a foreach statement, you use the $variable_name ____________________ to access the value of the element that is available in an iteration.

You will not receive an error if you attempt to use a foreach statement with any variable types other than arrays.

A ____ statement is used to iterate or loop through the elements in an array.

With the ____________________ statement the program assure that the file is added to the script only once and halts the processing of the web page and displays an error message if the include file cannot be found.

A switch statement contains the following components: the keyword switch, an expression, an opening brace, a case label, the executable statements, the keyword ____________________, a default label, and a closing brace.

A formal ____________________ is a variable that is used within a function.

You must include a(n) ____________________ to separate each section in a for loop.

The else clause can only be used with an if statement.

One of the primary differences between the while statement and the for statement is that in addition to a conditional expression, the for statement can also include code that initializes a counter and changes its value with each iteration.

case "Monday" is an example of a ____________________ data type being used as a case label.

The parameters within the parentheses of a function declaration are what kind of variables?

If you do not include code that changes the value used the by the condition expression, your program will be caught in a ____ loop.
