Exam 4: Selection

The logical AND operator is ____.

The evaluation feature for the && and || operators that makes the evaluation of an expression stop as soon as it is definitively determined that an expression is true or false is known as short-circuit evaluation.

One of the main advantages of using a switch statement is that it avoids using the equality operator, ==.

The switch statement usually results in more complex code than an equivalent if-else chain.

A relational expression consists of a boolean operator that compares two operands.

____ is not a relational operator.

The term "flow of control" refers to the order in which a program's statements are executed.

A ____ statement is a specialized selection statement that can be used in place of an if-else chain where exact equality to one or more integer constants is required.

A common practice for some programmers is to place the opening brace of a compound statement on the same line as the if and else statements.

The logical NOT operator is ____.

Including one or more if-else statements within an if or if-else statement is referred to as a ____ if statement.

Within a selection statement, an expression that evaluates to 0 or less is considered as false, while any positive is considered as true.

When an executing program encounters a(n) ____ statement, the condition is evaluated to determine its numerical value, which is then interpreted as either true or false.

The use of braces to enclose a set of individual statements creates a single block of statements, which may be used anywhere in a C program in place of a single statement.

It is a good practice to terminate the last case in a switch statement with a ____.

In C, relational expressions are evaluated to yield a boolean result.

When the ____ operator is used with two expressions, the resulting condition is true if either one or both of the two expressions are true.

The simplest C selection statement is the one-way if statement.

Indentation used within an if-else is critical to ensure that the code compiles correctly.

Any number of case labels may be contained within a switch statement, in any order.
