Help resolving errors on vscode

Hello,

I’m currently trying to learn C++ through a Udemy Course offered by one of the instructors( C++ Fundamentals: Game Programming For Beginners). I am having issues compiling my code due to two errors stating that it cannot find specific things that were downloaded directly from the links provided from the course. I tried download it once again and also deleted the old file and replacing it with the new ones, but the errors are still there. I have attached screenshots of the errors on vscode that I received. If anyone could help me it would be greatly appreciated.
