I bought a CD for Photoshop/Lightroom 6. Thanks everyone for your help, I have figured how to copy pics out of Photoshop/Lightroom!!
The short answer is, you right-click the image and pick "Export".
It helps to understand how Lightroom is handling your data.
When your import your RAW images into Lightroom, Lightroom treats them a bit like you might think of a physical film negative. Nobody "edits" the negative... they adjust and tweak the printing process to get the output they want without ever altering the original input.
Lightroom does the same thing... When you import your RAW files, they'll
never be changed or adjusted (you do have an option to convert them to Adobe .DNG but I recommend you do not do that... because if you ever want to take them out of Lightroom and switch to something else, you'll have to hope that the "something else" supports Adobe .DNG and not a lot of non-Adobe software supports .DNG files. Best to leave them in your camera's native RAW file format.)
So where are all the changes you make actually stored? As you make adjustments, Lightroom is keeping a list of all the adjustments you're making which it keeps in it's library. e.g. "he tweaked up the exposure by + .3 stops", "he adjusted the white balance down to 4800k", "he applied sharpening at a radius of radius and strength of __ and __." etc. etc. etc. When you view an image, Lightroom opens the original RAW and simultaneously looks at the adjustments you made and rapidly applies them to the image you see on screen. The version you SEE isn't actually stored in that form anywhere on your computer (although you can build "smart preview" images.)
The advantage is... suppose you later decide you want to change your mind about an adjustment you made. You can change it's value at any time or remove an adjustment completely (independent of all other adjustments.) This isn't the same as an "undo".... for example if I make adjustment #1, then make adjustment #2, then decide to remove adjustment #1 it will not impact adjustment #2 (you don't back out everything you did back to the step you want to remove - you can edit them out of order.)
With all of this in mind... what you are looking at on the screen is basically a "version" of your edit. If you like that version, you can export it.
Right-click on the image and pick "Export..." and you can set all the properties... type of export (e.g. JPEG, TIFF, etc.) resolution (described as a "fit within" which really means it will maintain proportions but the longest edge wont be longer than the size you specify), and so on. If you want a watermark, this is when it would be applied (they are only added when you "export" your image). ... you can also select a many images and they'll be exported with the same properties. There is also an "export with previous" which will just do an export using whatever settings you used last time (it wont ask you). So if you're not changing your export properties, it's a short-cut.
There are lots of tutorials on how to use Lightroom.
