Deleting a reference

Question

Is this valid? An acceptable practice?

typedef vector intArray;

intArray& createArray()
{
    intArray *arr = new intArray(10000, 0);

    r         


        

Answer 1

It's valid... but I don't see why you'd ever want to do it. It's not exception safe, and std::vector is going to manage the memory for you anyway. Why new it?

EDIT: If you are returning new'd memory from a function, you should return the pointer, lest users of your function's heads explode.
