What is the most efficient way to append one std::vector to the end of another?

After a lot of arguing (and a reasonable comment from Matthieu M. And villintehaspam), I'll change my suggestion to.

Probably better and simpler to use a dedicated method: vector.insert.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
