cpanel

If your host doesn’t have cPanel, it should have something similar (Plesk or so) that should have the same functionality. Alternatively you can unpack zip file on your hard drive and upload unpacked files and folders to your hosting (all of them!).
You should also check whether your hosting offers automatic WordPress installation through Softaculous or something similar.

I tried to upload the files unpacked but a lot of files fall off through transferring by filezilla. I asked here what to do and I was told to upload the files as a zip file and to unpack it on cpanel.
For example, I’m using 000webhost free hosting to understand everything before I’m buying my own domain. They say in their website they use cpanel, so my question is how do I get access to the cpanel? Is it through phpadmin?

When you login to your 000webhost account you should get this:

From there you see “File manager” on top and you see “Manage website” towards bottom. If you click on that, one of the options will be to install WordPress automatically.

Got it, thank you very much. one last thing – I heard a lot of people talking about cpanel that looks like this:

I’ve heard you can manage your website and your database from there. can I have an access to this menu through 000webhost or they got their own interface? and if I’m buying a domain, do I have to make sure I’m getting cpanel too? and they will guide me how to get to this cpanel menu like in the image above?

Well, cPanel is kind of a “standard” panel when it comes to shared hosting. Once you learn to manage things through it, no matter what host you chose provided that it has cPanel, you’ll know what to do.
000webhost used to have it but after the hacking incident they’ve changed it to its own version. I don’t think they offer classic cPanel even for paid hosting. Check with them. Bluehost has its own, GoDaddy own version as well, as far as I know.
Personally, that approach is like reinventing a wheel, and I tend to stay out of such hosts.

alright, thanks a lot ??
