Return array in C++

Question

I am a total C++ noob, and I am having some trouble returning an array from my methods. I have a header file with the following method declaration:

virtual d

You'll better use std::vector or if you really want to return a plain array, return a pointer (to such an array) dynamically allocated with e.g.

double* arr = new double[arrSize];
// fill arr appropriately
return arr;

But I'll recommend returning a std::vector instead.
