Question 1

After the statements in a loop are performed, the condition is evaluated again; depending on the evaluation's outcome, the statements might be performed again.

Accepted Answer

In a loop, after executing the loop's body (the statements inside the loop), the condition is checked again. If the condition still evaluates to true, the loop's body is executed again. This process repeats until the condition evaluates to false.

Question 2

Loops are commonly used to perform a task a specified number of times.

Accepted Answer

Loops are programming constructs used to repeat a block of code a specific number of times or until a certain condition is met, making them ideal for tasks that require repetition.

Question 3

Looping allows you to use one set of instructions to process multiple sets of data.

Accepted Answer

Looping in programming enables the execution of a set of instructions repeatedly, allowing for the processing of multiple sets of data without the need to write the same code over and over again.

Question 6

On a flowchart, if you have a condition leading to statements on the true branch (or on both the true and false branches), but the flowline does not go back to the condition, it is a While loop.

Accepted Answer

This description does not necessarily indicate a While loop; it could represent an If statement or conditional branch without a loop. While loops specifically involve repeating a block of code as long as a condition is true, typically requiring the flow to circle back to the condition.

Question 7

On a flowchart, if you have a condition leading to statements on the true branch, and the flowline goes back to the condition, it is an If (or If/Else) statement.

Accepted Answer

This describes a loop (such as a while loop or for loop), where a condition is checked and, based on the outcome, the flow may return to re-evaluate the same condition after executing certain statements, allowing for repeated execution based on that condition.

Question 8

With a determinate loop, you do not know the number of iterations ahead of time.

Accepted Answer

In a determinate loop, the number of iterations is known ahead of time, unlike in an indeterminate loop where the number of iterations is not predetermined.

Question 9

An infinite loop is one that never ends.

Accepted Answer

An infinite loop continues to execute without ever terminating, usually due to a condition that never becomes false or is never reached.

Question 10

Continue is a reserved keyword in many languages, so it cannot be used as a variable name.

Accepted Answer

In many programming languages, "continue" is a reserved keyword used within loops to skip the current iteration and proceed to the next iteration, hence it cannot be used as a variable name.
