initialize vector of pairs

Question

I wanted to initialize a vector of pairs with something like this

std::vector< std::pair<bool, bool> > myvector(initSequence.size(), X );

what shall I substitute in place of X, if I want to initialize every pair with (false, false)?

Thank you

Answer 1

std::pair<bool,bool>(false, false)

or

std::make_pair(false, false)

Answer 2

Nothing. std::pair<bool, bool> will be default constructed as make_pair(false, false).
