Why we use comments in programming?

Question

Is it mandatory to use comments?

Answer 1

Using Comments in our code is very helpful for the users reading our code...
Although it is not compulsory but yet you should insert comments like
<!--Table section started -->
Or
//Table section started
It also helps the coder writing the code in knowing where the table section started and where ended
...
/*
Note :
As many Comments in your code may make your code look bad ...
*/

Answer 2

Of course, short comment like "getting names from an array" is nice, but something like "looping an array with class members names and use it to..." is too long.

Answer 3

If you provide your program then comments help them to read your program..

Answer 4

On the other hand if the methods are short their names tell us a lot.

Answer 5

In my opinion code should be readable without comments. So use them when the situation requires it.

Answer 6

The usefulness of comments usually occurs to us a few months in.
When we look again at codes we wrote ourselves a few weeks ago.
And suddenly have trouble understanding how they even work.

Answer 7

They are like notes to readers of the code including the writer.

Answer 8

For youself and for future programmers, who maintain your code

Answer 9

Comments are not necessary.
They are used to make code more readable.

Answer 17

Barteker, but a one-line comment over a 'paragraph' of code, say over ten coherent lines of code that do one thing, can still make a code more readable, even if it's well written.
