Karel the Robot

Home Page

An excellent method for introducing students to computer programming is described by Richard E. Pattis in his book Karel the Robot. By initially limiting the student's language repertoire to easily grasped imperative commands whose actions are visually displayed, the Karel approach quickly introduces students to such concepts as procedures and the major control structures.

Although originally based on Pascal, the Karel approach has been used successfully with several different computer programming languages. These pages describe a version of Karel that uses the C / C++ language.
