Select all that apply. Which of the following cause(s) a statement or set of statements to repeat as long as a condition is true?
A) Do-While loops
B) While loops
C) Do-Until loops
D) For loops
Answer (2)
The loops that cause a statement or set of statements to repeat as long as a condition is true are A) Do-While loops, B) While loops, and C) Do-Until loops. For loops (D) do not meet this criteria as they run for a predetermined number of iterations. Therefore, the selected options are A, B, and C.

In computer programming, loops are used to execute a set of statements repeatedly based on a condition. Here's an explanation of each option provided:
A) Do-While loops : This type of loop will execute the set of statements at least once before checking if the condition is true. After the initial execution, it continues to repeat as long as the condition remains true. Therefore, a Do-While loop can cause a statement or set of statements to repeat as long as a condition is true.
B) While loops : This loop checks the condition before executing the statements. If the condition is true, it runs the statements and continues to loop through them repeatedly as long as the condition is true. Therefore, a While loop fits the criteria where execution continues while the condition is true.
C) Do-Until loops : Though similar to Do-While loops, a Do-Until loop continues to execute until a specified condition is true (meaning the loop runs while the condition is false). Therefore, a Do-Until loop does not fit the criteria specified in the question.
D) For loops : This loop is primarily used when you need to iterate over a range or collection with a known number of iterations. A For loop operates based on a counter and is not primarily driven by a condition that remains true, but rather continues until the counter reaches a specific value.
Based on the explanation above, the types of loops that cause a set of statements to repeat as long as a condition is true are:
A) Do-While loops
B) While loops
