vector remove cpp 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: 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 3: c++ remove element from vector
vector.erase(position) // remove certain position
// or
vector.erase(left,right) // remove positions within range
