How to insert a new node in a linked list in C++? (at the front, at the end, after a given node)

In this video I'll explain three different ways to insert a new node into a linked list:
- Insert a node at the front of a linked list
- Insert a node at the end of a linked list
- Insert a node after a given node
You can find the simple linked list from the start of the video in the pinned comment.

Why not all the code at the end.

When we are inserting a node after specific node, why are we not passing address of previous node in the function insertAfter?

You are the best Code teacher I've come across Miss Saldina. Teachers like you are what we need. Taking us step by step through concepts with very detailed explanations and implementations. You are just outstanding. Truly impressive work.🥳. You are appreciated all the way from South Africa.

This definitely helps me to understand the linked list. I searched a video on KZbin that is spoken in my mother language but all of them were much difficult than yours. In addition, they were too generalized from the beginning, but this point-by-point lecture makes me understand well.
