Which is correct: vector OR const vector?

I want to create an std::vector of std::stri

Answer 1

If your only choices are those two and you want the program to compile, use const std::vector<std::string>.

If you don't mind compilation errors (both on GCC4.8 and Clang), probably due to the fact that const std::string does not meet the requirement of CopyAssignable (prior to C++11) or MoveAssignable (since C++11), even though, apparently, it's mostly because it's not Destructible, use std::vector<const std::string>.
