    Study Notes

    Evolution of Programming Languages

    • First generation - Machine language; the only language computers understand without translation
    • Second generation - Assembly language; low-level language using brief abbreviations for instructions
    • Third generation - Procedural languages, high-level languages specifying what to do and how; combines structured and modular programming
    • Third generation - Object-Oriented Programming (OOP) languages; uses classes of objects with inheritance
    • Fourth generation - Non-procedural, high-level languages using English-like representation, close to human language

    The Programming Process

    • Phase 1 - Defining the Problem - clearly stating the goal and understanding the problem
    • Phase 2 - Designing the Program - creating a plan, using pseudocode or flowcharts
    • Phase 3 - Coding the Program - translating the plan into instructions using a programming language
    • Phase 4 - Testing and Debugging the Program - finding and correcting errors
    • Phase 5 - Implementing and Maintaining the Program - testing by users, documenting, maintaining, and evaluating

    Algorithm

    • Pseudocode - uses plain English to mimic program instructions
    • Flowcharts - use symbols to represent program logic and flow

    Debugging

    • Bugs - errors in code
    • Debugging - process of finding and correcting errors
    • Desk checking - reviewing code line by line to spot errors
