Question 7

Expressions that are tested by the if statement are called Boolean expressions.

Accepted Answer

Boolean expressions are expressions that evaluate to either true or false, making them ideal for use in if statements which require a true/false condition to execute the code within.

Question 9

An action in a single alternative decision structure is performed only when the condition is true.

Accepted Answer

In a single alternative decision structure, the action is performed only when the condition is true.

Question 10

The not operator is a unary operator and it must be a compound expression.

Accepted Answer

The not operator is a unary operator, but it does not necessarily need to be a compound expression. It can also be applied to a single expression, such as "not x" where x is a boolean variable or expression.

Question 11

Accepted Answer

The answer of The logical _______________ operator reverses the truth...

Question 14

Short-circuit evaluation is performed with the not operator.

Accepted Answer

Short-circuit evaluation is not applicable to the 'not' operator because it only operates on a single operand, whereas short-circuiting involves evaluating multiple operands in logical expressions like 'and' and 'or'.

Question 15

Decision structures are also known as selection structures.

Accepted Answer

This statement is true. Decision structures are also referred to as selection structures because they allow a program to choose among different alternatives based on certain conditions or criteria.
