Question

Identify the false statement.

a. When one if statement follows another, the first else clause encountered is paired with the first if that occurred before it.
b. Statements in which an if structure is contained inside another if structure commonly are called nested if statements.
c. A complete nested structure always fits entirely within either the if portion or the else portion of its outer statement.

Answer 1

Statement a is false; an else clause is paired with the nearest preceding if statement that lacks an else. Statements b and c are true, correctly describing nested if statements and their structure in programming.

Step-by-step explanation:

In the context of conditional statements within programming, we come across various structures that handle decision-making. Analyzing each statement individually, we can determine the truthfulness of each.

• Statement a: When one if statement follows another, the first else clause encountered is paired with the first if that occurred before it. This statement is false. The else clause is actually paired with the most recent unmatched if that has no corresponding else.
• Statement b: Statements in which an if structure is contained inside another if structure commonly are called nested if statements. This statement is true.
• Statement c: A complete nested structure always fits entirely within either the if portion or the else portion of its outer statement. This statement is true.

To correct the false statement (a), the accurate version would be: An else clause is paired with the nearest preceding if statement that is without an else.
