12. Evolution of Programming Languages Office Automation David Asirvatham First Generation 1940s (Machine language) Difficult to learn and use Long instructions Machine Dependent Second Generation 1950s (Assembly language) Difficult to use for large programs Shorter codes than ML Machine Dependent Third Generation 1950s (COBOL, C++) English-like Problem Oriented Easy to use Fourth Generation 1980s (Foxpro, Dbase) More English-like Many Functions Incl. Data Management Easy to use Natural language Future Use of natural language Voice-recognition
