how to remove an element from a vector by value c++ code example

Example 1: remove value from vector c++

#include 
#include 

// using the erase-remove idiom

std::vector 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: how to remove an element from a vector by value c++

std::vector v; 
// fill it up somehow
v.erase(std::remove(v.begin(), v.end(), 99), v.end()); 
// really remove all elements with value 99

Example 3: c++ remove element from vector

vector.erase(position) // remove certain position
// or
vector.erase(left,right) // remove positions within range

Example 4: 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());

Example 5: remove element by value vector c++

#include
using namespace std;
int main(){
    vector v;
    //Insert values 1 to 10
    v.push_back(20);
    v.push_back(10);
    v.push_back(30);
    v.push_back(20);
    v.push_back(40);
    v.push_back(20);
    v.push_back(10);

    vector::iterator new_end;
    new_end = remove(v.begin(), v.end(), 20);
