Initialize a vector of pairs in one line

Question

I want to initialize a std::vector (of std::pair), with k objects, with the pair of values shown below.

Here is my attempt:

// int k
std         


        

Answer 1

You can just switch to { } around the constructor arguments...

std::vector<std::pair<Point::FT, int>> v{k, {std::numeric_limits<FT>::max(), -1}};

See it running here

Answer 2

Assuming Point::FT is something for which numeric_limits::max() is valid,

std::vector <std::pair<Point::FT, int>>
        v(k, std::make_pair(std::numeric_limits<FT>::max(), -1));
