4 Introduction  Early days of computing Programmers used assembly language  Programs written by technically oriented people  In this presentation, we provide an illustrative introduction to high- level programming languages, through covering the following aspects: Computer System Organization. Programming Languages Reference Framework. The Four Generations of Programming Languages. The Life Cycle of High-Level Programing.

14 High-level Languages  High-level programming languages Includes third-generation languages Overcame deficiencies of assembly language Programmer didn’t need to manage details of data storage or movement

15 High-level Languages  Expectations of a high-level language program (continued) Programmer can take a macroscopic view of tasks; “primitive operations” can be larger Program will be portable Code will be closer to standard English and use standard mathematical notation

16 Compilers Vs Assemblers
