You have completed the C++ course, so you probably know about the std::vector type.

It is almost always better to return a vector of strings in such cases since returning pointers to memory allocated inside a function is risky (because you might forget to release the memory since it wasn't allocated manually by you (this is called a 'memory leak', a very common error by programmers)).

In fact, std::vector should be preferred over manual heap allocation of arrays in almost all cases in C++.
