Cast object into vector's const_iterator

Hi I have a function which takes std::vector<T>::const_iterator as parameter.

Question is:

How can I cast standalone object of type T, into iterator, so I can use it as an argument?

You shouldn't be trying to cast an arbitrary object type T to std::vector::const_iterator.

Assuming the object is a std::vector<T>, you can use the std::vector::cbegin or std::vector::cend functions to get a std::vector::const_iterator.

You cannot. That standalone object needs to be stored in an appropriate container. Only containers provide creation of iterators.
