C++ - List Part 2: Adding and Removing Elements

std::list provides efficient methods for inserting and removing elements at any position.

Examples and Explanation

Adding Elements

myList.push_back(10);  // Adds 10 to the end

myList.push_front(20); // Adds 20 to the front

Explanation: push_back() and push_front() add elements to the end and the front, respectively.

Removing Elements

myList.pop_back();  // Removes the last element

myList.pop_front(); // Removes the first element

Explanation: Use pop_back() and pop_front() to remove elements from the respective ends of the list.

Inserting at a Specific Position

auto it = myList.begin();

std::advance(it, 1);  // Move iterator to the second position

myList.insert(it, 15);

Explanation: The insert() method allows inserting elements at a specific position using iterators.

Removing by Value

myList.remove(10); // Removes all elements with value 10

Explanation: The remove() method eliminates all instances of a specific value from the list.
