What is the difference between an editor and an interpreter? 1. An editor allows program files to be entered and modified; an interpreter reads and executes program files 2 An editor allows program files to be entered and modified; an interpreter produces an indexed database of terms and keywords 3. An editor allows program files to be entered and modified; an interpreter produces an organized list of files 4. An editor converts program files into an executable program; an interpreter allows program files to be entered and modified

An editor allows program files to be entered and modified; an interpreter reads and executes program files
