C++ instantiating std::vector<std::string> with fixed number of empty strings
c++, default, initialization, vector
Solution
Something like this:
std::vector<std::string> v(N);
where `N` is the number of strings. This creates a vector with `N` empty strings.
Problem
I'm developing a class for building records (with a fixed number of fields). My public methods allow the user to insert individual values by index. There's no requirement that the user fill in all fields -- so I'd like to preallocate the vector that represents the record to the exact size, with every field initialized to the empty string. Is there a way to do this more easily than with a push-back loop?
