STL container function return values

Question

When looking over the member functions of the STL containers, an odd thought occurred to me. Why don\'t functions like std::vector::push_back(T) not ha

Answer 1

I think it has to do with the concept of a return value: the return value is there not for your convenience but for a conceptual result of the 'computation' they apparently thought push_back conceptually doesn't result in anything.
