Convert a vector to initializer_list

Question

Everyone creates std::vector from std::initializer_list, but what about the other way around?

eg. if you use a std::initializer_list

Answer 1

I think that the best solution without templating obscure iterator classes for the good of passing vector using its two methods returning iterators is just to implement your function logic in a function taking vector.

void someThing(std::initializer_list items)
{
     std::vector v;
     for(int i:items)
     {
             v.push_back(i);
     }
     someThing(v);
}

void someThing(std::vector items)
{
...
}
