What does g++ do?

Short answer. Compiles the code into a program.

What do you do if there are errors?

Fix them and compile again.

Remember

g++ hello.cpp -o hello
Fix errors, then run

You saved your code. How does it actually run? Save the file. The compiler turns it into machine code. Errors? Fix them and compile again. Then run the program. Compile with G plus plus. Fix every error, then run.
