Loop statement

Before

Programming beginners are learning by themselves. Since it is in a state of groping, there may be a lot of things to do.

Purpose

As I proceeded with learning, when I expanded the learning language, I thought that even if I had done it in the past, the grammar would be confused and I would often search again, so it is rudimentary. I decided to leave it as my own memo even if it was something.

Loop statement
