Comenting

comment is a very important part for programming, we often write a lot of work in a lot of work that does not come to any work except just testing. Comments can be made in two ways, one is single line comment and the other is halo double line comment. You can write comments anywhere you want. Single line comment is // and double line comment is / * and at the end / *. Comments are used in another way that you can write a short summary of what you are doing so that when someone else sees your code can easily understand what you are doing.
