Which of the following are mutating-sequence algorithms defined in the STL?
A) copy
B) remove_if
C) find
D) Both a) and b).

Question

Quizplus · Accepted Answer

Both copy and remove_if are mutating-sequence algorithms defined in the STL. Copy creates a copy of the elements in a sequence, and remove_if removes elements that satisfy a given condition. Find, on the other hand, is a non-mutating algorithm that returns an iterator to the first element in a sequence that meets a given condition. Therefore, options A and B are the only ones that are mutating-sequence algorithms, and the correct answer is D.
