Hey Paul, I'd like you to thank for putting your energy into making this tutorial. It was really enlightening and it made me comprehend the concept much better. Keep up the awesome job.

You CAN declare a variable inside a for loop in C. Just use C99 or C11.

This scared me in the past to start with c++, but it's actually such a simple concept.

This is the clearest explanation I have ever seen on this particular item !

Thx Paul.
I recall Jullian Assange saying, "commitment requires sacrifice, courage is contageous". (The latter meaning if you surround yourself w/ your peers, courage is contageous).
This said, while learning to code, (we're ALWAYS students however), we forget previous lessons etc, the "commitment" part is, constantly reviewing what we may forget.
This said, THANK YOU for your great work here on YouTube.
Cheers

I remember being so intimidated by this when I started learning C++. But then I learned that I didn't need it at all and I forgot about it completely.
