Karel is a programming language created specifically for teaching programming to beginners. It was developed by Bill Duvall and Paul Resnick at the University of Michigan in the early 1980s.
Karel is based on the language Pascal, and borrows its syntax and structure. However, Karel is much simpler than Pascal, and is designed to be easy to learn and use. Programs written in Karel are called "Karel programs" or "Karel code."
Karel programs are written in a text editor, and are composed of a series of commands. Karel programs are executed by a "Karel interpreter," which is a program that understands and executes Karel code.
Karel programs can be written to solve various problems, such as moving a robot through a maze, or sorting a stack of blocks. Karel is also sometimes used to teach programming concepts such as recursion and iteration.
