remove an element from poistion in a vector c++ 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: how to remove an element from a vector by value c++
std::vector<int> 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
