How to get position of a certain element in strings vector, to use it as an index in ints vector?

Question

I am trying to get the index of an element in a vector of strings, to use it as an index in another vector of int type, is this possible ?

Answer 1

If you want an index, you can use std::find in combination with std::distance.

auto it = std::find(Names.begin(), Names.end(), old_name_);
if (it == Names.end())
{
  // name not in vector
} else
{
  auto index = std::distance(Names.begin(), it);
}
