Boolean variables

Boolean variables

• A. are used with True/False or Yes/No answers
• B. store integer counters
• C. hold long text strings
• D. store unrelated data

Answer: (A)

Boolean variables represent truth values. They are used to store results of tests or conditions, which are typically true or false. This makes them ideal for answers like yes/no or true/false in decision-making code, such as controlling which branch a program takes in if statements or deciding whether a loop should continue. They are not meant to hold numbers, long text, or arbitrary data—that's what integers, strings, or other data types are for. A boolean models binary decisions, for example isEligible = true or false depending on whether the criteria are met.
