CompTIA PenTest+ (PT0-002) — Question 248

In Java C/C++, variable initialization is critical because:

Answer options

• A. the unknown value, when used later, will cause unexpected behavior.
• B. the compiler will assign null to the variable, which will cause warnings and errors.
• C. the initial state of the variable creates a race condition.
• D. the variable will not have an object type assigned to it.

Correct answer: A

Explanation

The correct answer is A because using an uninitialized variable can lead to unpredictable behavior in the program. Option B is incorrect as compilers do not assign null by default in all cases, and options C and D are irrelevant to the concept of variable initialization in this context.
