@abirbhattacharya82 Nice work. Take a look at this as well:

The scanf() family's %s operation, without a limit specification, permits buffer overflows (CWE-120, CWE-20).

Specify a limit to %s, or use a different input function.

Hey @abirbhattacharya82!

Sorry for the delay in getting back to you. I must have dismissed the notification accidentally. Could you look at the Codacy analysis results for your PR and resolve them? I will merge your PR once you are done with it.

Hey @abirbhattacharya82! Any updates?
