Been trying to code a chat window for a website kind-of like facebooks PC version (not messenger) does anyone have any idea how?

Answer 1

First get a programming tool/app for C++ , and get the correct API package(for the following chat, different chat has different API packages). Afterwards, research how the package works and slowly make your way through. Finally, you can code the page with HTML and attach the chat in the page.
[Dont worry if you dont know anything about the API package or how to make one, just ask the people who know how to use it. In fact, youtube/google is your best bet]

Answer 2

thank you, I've been trying to figure it out for a while now but that was the most informative answer I've had.
