Programming would mean to create scripts or applications to do some specific tasks.
The topics you refer to appear to be questions about how to use a Linux system, Suse in particular. When you login to your user account, you should be able to find the available application in the main menu. Where that menu exactly is, depends on the window manager in question. Should be KDE for Suse by default.
Even if you don't see Yast in the menus, but you can open a terminal, then you should be able to run
su will allow you to switch to the root user mode, and yast2 launches Yast.
Maybe you need to login as root to have Yast available in the menus. I'm not sure, it's been a while since I used Suse for the last time.
