vector remove element c++ by value code example

Example 1: remove value from vector c++

#include <algorithm>
#include <vector>

// using the erase-remove idiom

std::vector<int> vec {2, 4, 6, 8};
int value = 8 // value to be removed
vec.erase(std::remove(vec.begin(), vec.end(), value), vec.end());

Example 2: c++ vector remove element by value

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