c++ remove from vector by index code example
Example 1: remove element by index from vector c++
vec.erase(vec.begin() + 1);
vec.erase(vec.begin() + 1, vec.begin() + 3);
Example 2: c++ remove element from vector
vector.erase(position)
vector.erase(left,right)
Example 3: remove element by index from vector c++
auto removeByIndex =
[]<class T>(std::vector<T> &vec, unsigned int index)
{
vec.erase(vec.begin() + index);
};
std::vector<std::string> stringvec = {"Hello", "World"};
removeByIndex(stringvec, 1);
std::vector<unsigned int> intvec;
intvec.push_back(33);
intvec.push_back(66);
intvec.push_back(99);
removeByIndex(intvec, 2);
Example 4: vector erase specific element
template <typename T>
void remove(std::vector<T>& vec, size_t pos)
{
std::vector<T>::iterator it = vec.begin();
std::advance(it, pos);
vec.erase(it);
}
