Comments in any programming are used to explain the code and to make it more readable of developers.
Sometimes it is also useful when we quickly want to comment-out a code block to stop its execution during testing or debugging our codes.
Single-line comment are use to comment on one full line or a part of a line.
We can use single-line comment to explain a code in the same line or use it in debugging by comment out a code to prevent its executions.
To write a single-line comment, we have to start the text after two forward slashes
Lets see some example.

The comment blocks start with two symbol:
