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

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