— Ohk... Thanks👍
— I've been using Ubuntu for a year, I think I can now handle Debian if it's more stable
— Pretty good, you should try it (if you haven't yet) and maybe you'll like it more than Ubuntu.
Debian stable is released every 2 years and it receives only security update. If you are concerned about stability you can try the latest ubuntu lts that is supported for 5 years
— Ubuntu 18.04.2 LTS is current LTS
— .2 at end is just an iso with all updates.
— Until when it has support? Currently I have 18.10 version but want to switch to an LTS version
— 18.10 will have supported til July 2019, 18.04 will have support til 2023 at least.
— Hey I want to have the programme of C and C++ What can I do ?
— Download it
— Download some RAM from the internet
— Good, I'll install Ubuntu 18.04👌
— This makes everything clear
— If you're asking "I want to know how to code C and C++ on my PC", you'll have to download a compiler, should use a good text editor to write code. Google is your friend
