A do while loop is very similar to a while loop.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A do while loop is indeed very similar to a while loop. Both loops are used for repetitive execution of a block of code based on a condition. The main difference is that in a do while loop, the block of code is executed at least once before checking the condition. After the first execution, the condition is checked, and if it is true, the loop continues. If the condition is false, the loop is terminated. This behavior makes the do while loop suitable for situations where the block of code needs to be executed at least once, regardless of the condition.Rate this question:

The continue keyword is used in loops to skip right to the test condition.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The continue keyword is used in loops to skip the current iteration and move directly to the next iteration, without executing any further code within the loop for that iteration. This allows the loop to skip certain iterations based on a specific condition, and continue with the next iteration. Therefore, the statement "The continue keyword is used in loops to skip right to the test condition" is true.Rate this question:

The Return Statement is optional.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The return statement is optional in programming languages. This means that it is not always necessary to include a return statement in a function or method. If a return statement is not included, the function will still execute and perform any other actions or calculations specified within it, but it will not return a value. Including a return statement allows the function to return a specific value or result back to the caller. However, if a return statement is not needed or desired, it can be omitted.Rate this question:
