Erase-remove idiom: what happens when remove return past-the-end-iterator?

I would think v. Erase(v.end(), v.end()) would be well defined and erase nothing.

The C++ standard says that the erase(q1,q2) member "erases the elements in the range q1,q2)" (cf. Section 23.1.1). Since the range excludes the last element.

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.
