How to use the Pen Tool

I learned how to use the pen tool. With the pen tool I learned how to draw a C- shaped curve, an S-shaped curve. Really just the basics in illustrator. First you draw a straight line with the pen tool. Then drag in a direction opposite to the previous direction line. Then release the mouse button.
To create an S‑shaped curve, I dragged in the same direction as the previous direction line. Then released the mouse button.
