How do I append an element to a list in C++?

How do I append an element to a list in C++?

In C++, you can use the push_back() method to append an element to a list. For example, if you have a list called myList, you can do myList.push_back(newElement);.

What if I want to insert an element at a specific position?

You can use the insert() method for that. For example, myList.insert(myList.begin() + index, newElement); will insert newElement at the specified index.

Can I append multiple elements at once?

Yes, you can use the insert() method with an iterator range. For example, myList.insert(myList.end(), otherList.begin(), otherList.end()); will append all elements from otherList to myList.

Are there any performance considerations I should be aware of?

Yes, appending elements to a list is generally efficient, but inserting at the beginning or middle can be slower due to the need to shift elements.
