Why don’t you simply try doing that ? Or why don’t you Google search ?

sir,like this:

set st;
st.insert(5);
st.erase(4);

First check whether that element is included in set or not, and then erase, like this:

set <long long> st;
st.insert(10);
if(st.count(8) == 0) {
    cout << "Element not found" << endl;
else {
    st.erase(8);
    cout << "Element found" << endl;
}
