how to remove element from a vector in c++ code example

Example 1: remove element by index from vector c++

// Deletes the second element (vec[1])
vec.erase(vec.begin() + 1);

// Deletes the second through third elements (vec[1], vec[2])
vec.erase(vec.begin() + 1, vec.begin() + 3);

Example 2: vector remove class

carVec.erase(std::remove_if(carVec.begin(), carVec.end(), [&id_to_delete](const Car& ele)->bool
            {
                return ele.getnewId() == id_to_delete;
            }), carVec.end());
