WebApr 9, 2024 · v1 [0] is an lvalue referring to the first element of the vector, and std::move (v1 [0]) is an rvalue referring to that element. The move has little to do with the behaviour of the example. But the elements of v2 aren't references. They are integers. So, you initialise the non-reference second element of the vector using the value of the first ...
