Study Notes

  • PROGRAMMING 621

Programming Languages Paradigm

  • Paradigm describes a method to solve a problem or do a specified task.
  • Programming paradigm provides an approach to problem-solving using a programming language with available tools and techniques.
  • Two popular programming design approaches: Structured and object-oriented.
  • Imperative programming describes how a program executes, step by step, using command imperatives and mutable or immutable data.
  • Declarative programming describes what programs are to be executed, focusing on results and computation logic rather than step-by-step instructions, using end results, and focusing on the logic.
  • Examples of imperative programming languages are Fortran, C, and C++.
  • Examples of declarative programming languages are Miranda, Erlang, and Prolog.
  • Structured design is dividing a problem into smaller subproblems and analyzing each to find a solution.
  • Structured programming implements structured design by combining solutions to subproblems to solve the overall problem.
  • Structured-design is also known as top-down, bottom-up, stepwise refinement, and modular programming.
  • Object-oriented design (OOD) identifies objects as components, relevant data, and possible operations
  • The final program has interacting objects.
  • Object oriented programming language (OOP) implements OOD. Examples of objects include a DVD, or a customer and include operations like checking the name of the movie, reducing the number of copies in stock by one, or incrementing copies when a customer returns a DVD.
  • Each object consists of data and operations, combined into a single unit.
  • A class allows you to combine data and operations.

Problem Analysis-Coding-Execution Cycle and Processing

  • Programming is a process of problem-solving, where techniques are outlined and give insight into solutions that can be modified.
  • One technique is analyzing the problem, outlining its requirements, and designing an algorithm or steps to solve it.
  • An algorithm is a step-by-step problem-solving process with solutions for a fixed time
  • Three steps: Analyze and outline problem and its solution, implement and verify the algorithm, and maintain the program.
  • Three stages: start by analyzing it, then design an algorithm, then code the program in a high-level language.
  • Program requirements include interaction, data manipulation, output, and data representation.
  • A complex problem needs division into subproblems and analysis of subproblem requirements.
  • Correctness of an algorithm gets confirmed with sample data or using a mathematical analysis.
  • Programming code converts algorithm to programming code and then uses a text editor to enter the code; then the code gets run through a compiler
  • Correctness is verified by running code through a compiler.
  • Errors in code needs identification before it is removed to be re-run through the compiler
  • When syntax errors are removed, a compiler generates machine code which gets linked with the system and loaded into main memory for execution
  • Code produces guarantee in a language but not the guarantee that that program will run as expected
  • During executions, programs might terminate abnormally related to logical errors as a result of division by zero.
  • Even if a pro
