2
Common Misconceptions

• 1. This is a just C course
• - You will learn some C
• - Much more to get out of it
• - Developing software to solve problems

3
Common Misconceptions

• 2. Computers are smart
• They aren't
• Fast, and accurate, do as they're told
• Moral
• If you can't solve a problem with pencil and
  paper, the computer can't solve the problem
  either.

4
So, what is this class?

• We are going to
• Get comfortable with a development environment
• Learn about the development process
• Learn a programming language
• Learn some fundamental and useful algorithms

5
Software?

• Where does it come from? Where does it go?
• Can I buy one?
• Software begins as a concept.
• This must find its way to a computer...
• Software Development
• How does a concept get from me to you?

6
Software

• Use a programming language to explain our idea to
  the computer
• Computers don't understand English (yet)
• Utilities allow us to communicate to the computer
  (development environment, etc) Properly.

7
Development

• Main Tools
• 1. Editor (NOT a word processor)
• Write our software
• 2. Compiler
• Convert our software into a machine language
• 3. Debugging / Debugger
• Ensures we properly conveyed our software concept

8
IDE

• An Integrated Development Environment bundles
  together these elements.
• Microsoft Visual Studio
• Eclipse
• Dev-C
• NetBeans
• XEmacs

9
Algorithms

• Algorithms and Programs are not the same
• 1. An algorithm is a procedure for doing
  something
• Concept
• 2. A program is an implementation of an algorithm
• (virtual) Entity

10
This Course

• Will introduce you to C in detail
• Lay a solid foundation for further C /
  programming classes
• Enable you to use a computer to solve many
  real-world problems
