About C + + post-tail iterators: ++end ()

It is customary to say what ++v.begin () and--v.end () are used to, but what happens to ++v.end ()?
Come up with a simple code

vector<int> v;++v.end();

Error occurred during VS2017 debugging

The description end () iterator is not additive.
And here's what happened to me:

#include <iostream>#include <set>using namespace std;int main() {    set<char> st;    st.insert('a');    st.insert('b');    st.insert('c');    if ((st.find(0)) == st.end()) {        cout << "YES" << endl;    }    else {        cout << "NO" << endl;    }    getchar();    return 0;}

The same error occurs in debug mode.
But vs and GCC do not behave the same. In release mode vs generated program output is yes, and GCC produces no. Visible ++end () This behavior belongs to undefined behavior and needs to be avoided when considering boundary conditions.
