Which of the following is listed as a type of loops?

• A. for, while, do-while, for each
• B. while, for, if, else
• C. repeat, until
• D. for, while, do-while, for each, map (if, if else)

Answer: (D)

Loops repeat a block of code to process elements or perform actions multiple times. The traditional ways to loop include for, while, do-while, and for each, which cover counting, condition-based repetition, and iterating over collections. In many languages, a functional approach like map also serves the same purpose: it applies a function to every element of a collection, effectively looping through the items to produce a new result. The note that map can use a function containing conditional logic (if, else) highlights how you can tailor what happens for each element inside that loop-like pattern. Because this option encompasses both the classic loop constructs and a common functional looping pattern, it best represents the types of loops. The other choices miss one or more loop forms or include non-loop statements like conditionals.
