See Reference to function Instantiation problem please help I am desperate

So I’m just starting to learn C++ with no prior experience. I followed the course until the Hello World part. For some reason, the code compiled but gives me this weird error

I browsed a little on this site and tried using the /EHsc solution, but the cmd doesn’t display the Hello World.

can you please explain the solution as simple as possible? I have no prior coding experience.

Dupe: Hello World compiles but doesn't display Hello World
