Tons of Errors

I just started and I wrote about 30 lines of code to a tutorial. I tried running it after adding a few more lines and it gives me 150+ errors. When I look at the source, it brings me to some of the components. It then renders ever more errors. I have tried verifying the installation of UE4, but nothing changed.

hey, i cant follow you. could u send screenshots. And why did you try to verify the installation of ue4. If it worked before you wrote the few more lines you should tell what kind of code you added at least to it
