How to check that an element is in a std::set?

Question

How do you check that an element is in a set?

Is there a simpler equivalent of the following code:

myset.find(x) != myset.end()

Answer 1

Write your own:

template
bool checkElementIsInSet(const T& elem, const std::set& container)
{
  return container.find(elem) != container.end();
}
