I followed all your videos in this playlist, and they are wonderful. thank you.

[@lgodlike2324]

Wonderful explaination, thank you very much !

[@tonykososki3016]

Hey very well explained, just that "commercial" in the middle is a bit too loud and too surprising in my opinion. Some people may no like it :p

[@a54716]

very well explained

[@sania1592]

great

[@gmdstyles312]

How do I do so that after executing execlp the main method does not close but it can continue executing other things :c

[@jreinhart]

The content of the video is great, but the volume increase of your "subscribe" message around the 4 minute mark was jarring. Could you normalize that to be the same volume level as the rest of the video?

[@iFocusInstitute]

Thank you for the suggestion. I'll surely do it in further videos!

[@HardCorn12]

that was a jump scare for sure lol

Hello!!! Could You say please, how can I use exec function to call python script from my c++ program?They both are in the same directory. I suppose I should write something like execl("python", "python", "main.py", NULL); but it doesn't work((( Thank You in advance!!!

[@rashidsiddqui]

it should be python3, instead of python
