What Is Programming?• Crafting a set of instructions to solve a

problem• Analogy: cooking recipes

What Is Programming?

• Who “reads” computer programs?– The physical computer– Humans (yourself, your coworkers,

your instructor)

• Must be clear and well-structured• Programming with pen and paper

June 19, 2008 5

• Learn the basic components of computer programming– can be applied to any programming

language (Java, C++, etc.)

• Is COMP 110 right for you?– Require basic computer skills– No programming knowledge assumed

• Math, algebra

About COMP 110

Is COMP 110 Right for You?

• Do you have web programming experience with Java, perl, php?

• Experience with “classes” in C++?• Some experience with Matlab, Mathematica?• Do you know what is meant by Object, method,

member variable, recursion, array, sorting algorithms?

If yes to any, you may be ready for COMP401 instead.

Collaborating• You can

– talk to each other about the lecture topics– talk about assignment requirements– work in groups during recitation on recitation

assignments only• You should

– do your own assignments -- design and code• You should never
