How to initialize a vector of pair of string,string in a c++ class?

Question

How do I initialize a vector of a pair of strings in a C++ class? I tried several things but none worked out.

vector<pair<string,string>> myVec(); //doesn't work

Answer 1

There is no need to initialize a vector such a way

vector<pair<string,string>> myVec(); 

It is a function declaration with name myVec that does not have parameters and has return type vector<pair<string,string>>

It is enough to write simply

vector<pair<string,string>> myVec;

because in any case you are creating an empty vector.

Or if you want that the vector had some initial values and your compiler supports C++ 2011 then you can also write for example

std::vector<std::pair<std::string, std::string>> myVec =
{
    { "first", "first" }, { "second", "second" }, { "third", "third" }
};
