This post will discuss how to initialize a std::pair in C++... A simple solution to create a std::pair is using its initialization constructor, which takes two arguments corresponding to the first and second member of the pair respectively.
DontInit<int[100]>>p{1,{}};for(inti=0;i<100;++i)printf("%d ",p.second.u[i]);printf...

This constructor participates in overload resolution if and only ifstd::is_constructible_v<T1, U1>andstd::is_constructible_v<T2, U2>are bothtrue. This constructor isexplicitif and only ifstd::is_convertible_v<constU1, T1>isfalseorstd::is_convertible_v<constU2, T2>isfalse. ...
