Size of vector
-
I have declared
std::unique_ptr<std::vector<std::unique_ptr<Album>>> m_albums;
but when I try to find the number of elements by calling
m_albums->size();
it leads to a crash, presumably because no memory is not yet allocated for m_albums. What is the correct way out of this, so that I can call
m_albums->size();
even before adding any elements to the the vector? -
C++ Basics - you forgot to initialize your shared_ptr.
But why to use a shared_ptr in the first place here?
