  14. Course Objectives and Content

  15. Course Objectives • The objective of this course is to master problem solving using computer programing with C++ structured style.

  16. Course Learning Outcomes • Analyze a computational problem and develop a solution strategy to solve it. • Develop the needed algorithms to solve the problem and program the solution in C++. • Develop medium size programs in C++. • Understand the basic concepts of structured programming using C++. • Practice basic debugging and good coding skills. • Practice team work.

  17. Why C++? • Why not Python? • Why not Java? • Why not C#? • Why not C?

  18. Q1: How many languages exist? • Give a guess ? • 10, 20, 50, 100, …… ? • What do you think? • 2000 ~ 3000 • http://wiki.c2.com/?HelloWorldInManyProgrammingLanguages • http://www.99-bottles-of-beer.net/ • https://www.randstad.ca/job-seeker/job-tips/archives/comparing-11-popular-coding-languages_530/

  20. Before C / C++, B Programming Language • https://en.wikipedia.org/wiki/B_(programming_language)

  21. After C/C++, D Programming Language • https://dlang.org/

  22. Q3: Who are the news kids in the block? • Name three new languages ? • Lua, Koteln, Swift, Julia, R, ….. • How many languages should I know?

  23. Evolution of Programming • Machine Languages • Reflect hardware structure not programming ease • In 1955+, John Backus: Can we write programs like we write math formulas? • Formula Translation (FORTRAN) • IBM: Can we write code like we write English? • Common Business Oriented Language (Cobol)
