erase and remove in C++ standard library

• erase (iterator): uniform erase method.

// erase single position
c.erase(c.begin());
// erase range
c.erase(c.begin()+2, c.begin()+5);
 
// Erase during iteration
for (auto it = c.begin(); it != c.end(); ) {
    if (*it % 2 == 0)
       it = c.erase(it);
    else
        ++it;
}

• erase (key): set, map, multiset, (all elements with the key equivalent to key)
