Oh, I actually want to program in c language on a computer without a network, so I won't be distracted to do other things, and I will learn C language with one heart and one mind.

Ubuntu18.04 LTS offline installation via Iso image Is there a gcc compiler? Can I use it? I think the distribution has built-in gcc, because built-in gcc to compile the kernel.?
