Basic Programming Language Lectures for BE-Mechanical for TCS
TCS has started hiring for Season-2021 and Coding is one of the screening round of the process.
As coding practice is essential for Mechanical Students.

Note: Please join at sharp timing. 5 minutes late coming will be allowed. After that you will not be allowed in the Google Meet Session.
Please help me and yourself.

Due to some technical issue, Google Meet Video Session has not been recorded!! And facebook allowed me to broadcast this session for 07:41 minutes. Sorry for the same.
Unfortunately!!
OBS got stopped due to Network issue. I could not Broadcast Live session.
But this was great learning for me!!!
I tried to use Google Meet, Facebook Live and OBS together but system became very slow.
Small Experiment got failed!!!
But session was conducted through Google Meet 
. One more thing, I forgot to mark attendance for this session.
. One more thing, I forgot to mark attendance for this session.I discussed this issue with Prof. Antosh Dyade sir, as per his views there can be two issues:
1. RAM should be greater than or equal to 8GB for system.
2. Graphics Card is required for the Computer.
This is for your information. At the end internet connectivity got disconnected!!
Just I am sharing programs which have been discussed in the session. This will definitely help you get connected. Once again sorry for todays inconvenience.
