Console variables

Hey guys I’m starting to use C++ and I would like to know more about it. Can someone tell me how can I set these values and WHERE? Are these console variable? I really don’t understand where should they be set! Thankssss,the%20end%20of%20the%20frame.

These **CVar **are console variables.
In Unreal click: Window > Developer Tools > Output Log.
You’ll see the command bar at the bottom of the Output Log area.

So basically are they only for debugging?
