Just look at the function definition, the returned value is the iterator type! I did a test and found that the ERASE operation does not change the value of the iter, whether the parameter is passed in the past or returned! In fact, the erase operation of the vector is to delete the element itself, and then reorganize the data to generate a new vector!
vs may have protected the iter dereference operation after deletion, so cout << iter will have an error! This is not the case in Dev C++! Post the test** and the results and everyone will know the results.

Under include include.
Add contains: using namespace std; Add a standard namespace, as vector is defined under the std namespace.

Haha, the upstairs laughed at me, but it's also a way!
The functions of the vector container are very powerful, and it is not possible to implement them all casually, if you can easily implement them, then those engineers at Microsoft are too shameless! It can only be said that some of its functions can be simulated by means of structure, overload, etc.!

If you learn data structures, this is very easy, because there are more personal designs, so I won't write it, and the landlord will find some books on data structures to read.

No, even if there is, it makes no difference.
