Explanation

The '&&' operator executes the second command only if the first command exits successfully (exit code 0). Using 'mkdir CompTIA_doc && cd CompTIA_doc' ensures the directory is created before attempting to change into it - if mkdir fails (e.g., directory already exists with error), cd is never attempted. A single '&' runs the first command in the background and immediately starts the second, which would fail because the directory may not exist yet. '+' is not a valid shell operator. '||' is a logical OR, running the second command only if the first fails - the opposite of the intended behavior.
