CS 322 week 1

Read syllabus, group work, clustering-based grading (fair)Why software engineering: ABET, what’s wrong with code+fix Four generations of Programming Language: 1st: machine code—binary streams: CPU 50s 2nd: assembly—readable codes: english like code 3rd: procedural: 3 types C(2.5)/Cobol/pascal: wirth, Dijkstra/PL1 4th: OO: java 95% inheritance: reuse, localize, DB: SQL-like:

declarative (prolog) what to do; all other: how 3 prog. Paradigm: functional, imperative, logical58, MIT LISP Haskell/scala: no side effects, lazy: eager, first-class object (short) recursion func
