We use comments to describe
the working of our code to
others
and
our future self.
The comments are ignored
when the code executes.
Therefore,
they are not visible
in the output.
We can add single-line comments
using two forward-slash characters //.
In the example given below,
the comment fully
occupies the whole line.
Anything to the right side of
// becomes a comment.
In the example given below,
only the text on the right side
of // is a comment.
The code on the
left side works normally.
The comments should be kept
precise and meaningful.
