The precursors of object-oriented programming can be traced back to thelate 1960’s: Classes, inheritance and virtual member functions wereintegral features of Simula67, a programming language that was mainlyused for writing event-driven simulations. When Smalltalk firstappeared back in 1972, it offered a pure object-oriented programmingenvironment. In fact, Smalltalk defined object-oriented programming.This style of programming was so innovative and revolutionary at thetime that it took more than a decade for it to become a standard in thesoftware industry. Undoubtedly, the emergence of C++ in the early ’80sprovided the most considerable contribution to this revolution.
