C++ Vector of Maps using an iterator how to

Question

How can I populate a vector of map along with a rowID , or an iterator for each row of a valuepair Set

Like for example

typedef std::map

        

Answer 1

in short:

mapDB_vec.push_back(std::make_pair(0, mapDB_colVal));

longer:

you don't need that rowID, vector index is good enough

more longer:

struct Row {
    std::string x;
    std::string y;

    Row(std::string const& x_, std::string const& y_): x(x_), y(y_)
    {}
};

vector mapDB_vec;
mapDB_vec.push_back(Row("Apple", "Red"));
mapDB_vec.push_back(Row("Pear", "Red"));
