C++ Vector Pop Front Code Example

Example 1: c++ vector pop first element

std::vector<int> vect;  vect.erase(vect.begin());

Example 2: vector erase specific element

vector.erase( vector.begin() + 3 ); // Deleting the fourth element

Example 3: delete from front in vector c++

// Deleting first element vector_name.erase(vector_name.begin());  // Deleting xth element from start vector_name.erase(vector_name.begin()+(x-1));  // Deleting from the last vector_name.pop_back();

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); }
