Modular programming

Php programming: if, forall

Php programming: while loops

Mysql in wordpress

Recapping the main points

• A quick glimpse of a popular blogging platform• It uses php and MySQL• Novice users may not need to do any

programming• But using programming one can do lot more– Example: Change the way the archives show up

• Two kinds of programming– Php: Procedural; with an interpreter– MySQL: Declarative

Programming Languages• They come and go

– Fortran– Cobol– Pascal– ADA– Lisp– Java– C– C++ – Php– Ruby on Rail– SQL

• But basic concepts remain

Some basic programming language concepts

• Procedural constructs (C, C++, Java, php, etc.)– If - then – else– While – do– Repeat – Until– Procedure calls

• Object-oriented constructs (C++, Java, etc.)– Objects and methods

• Declarative constructs (SQL, Prolog)– Say what you want not how you want

• Functional constructs (Scheme, LISP)– Apply functions recursively

Beyond programming languages

• How do a large group of people collaboratively write a huge software?– Such as the wordpress platform

• How do we analyze large programs for its correctness?

• How do we test programs?

Relevant CSE Classes

• CSE 100: Principles of programming with C++• CSE 110: Principles of programming with Java• CSE 205: Concepts of Computer Science & Data Structures• CSE 220: Programming for Computer Engineering• CSE 240: Introduction to programming languages• CSE 310: Data Structures and Algorithms• CSE 340: Principles of programming languages• CSE 360: Introduction to Software Engineering• CSE 412: Database management • CSE 440: Compiler Constructions 1• CSE 445: Distributed Software Development• CSE 460: Software Analysis and Design• CSE 485-486: Computer Science Capstone Project

Our goal in these classes

• To help you to learn the basics, • Provide some specific examples,• Give you some development and presentation

experience, • But in general help you to learn how to learn

new things on your own in the future.

Take home task

• Create a wordpress blog• Personalize the default blog setting to your

liking• List what changes you made.• List some of the changes that you would have

liked to make but could not figure out how to make it.
