1. The Art of Programming

2. The process of breaking problems down into smaller, manageable parts By breaking the problem down, each part becomes more specific These individual solutions are combined to create a solution for the larger problem Problem Solving

3. Step 1: Determine what the output should look like Step 2: Determine the input needed to obtain the output Step 3: Determine how to process the input to obtain the desired output Problems with this approach? One Method: The Problem Solving Approach

4. Second Approach: Waterfall of Software Development

5. Use the problem solving approach (method 1) to define the problem Gives a clear idea of what the input looks like Defines the relations between the input and the final output Analyze: Defining the Problem

6. Find a logical sequence of precise steps that solve the problem. This sequence is called an Algorithm Every detail should appear, even the obvious steps Flowcharts, pseudo-code, UML Diagrams, and top- down charts can be used to help break the problem into smaller steps Test data should be run through the design to test its accuracy Design: Planning the Solution

7. Translate your design algorithm into computer readable code The choice of computer language depends on the needs of the program Code: Translation to Program

8. Locate and remove any problems in the code Testing is the process of finding the errors in the program: both logic and coding errors Debugging is the process of remove the errors found Test and Debug: Looking for Trouble

9. Updating the code to make sure it continues to function properly Reducing errors found after the code has been released Correcting issues with documentation (user manuals, websites, etc.) released to the public Maintenance: Keeping it Running

10. Documentation is necessary for both understanding code while developing software and conducting maintenance after software has been released Documentation can include comments made inside of the code, user manuals, development notes, or original design details. Documentation: The Key to Understanding

11. No going back to previous steps Perfect code every time! (yeah right…..) Assumes everything progresses in a linear fashion Can only be in one location at any time Always start from the beginning every time Problems With the Waterfall

12. The Iterative Approach: What Software Dev Really Looks Like

13. An English like representation of how the program language should function and mimics what the actual code will do Comprised of the words “pseudo” and “code” Pseudo meaning almost or imitation Code meaning the physical software code Pseudo-Code: The “Fake” Programming Language

14. Pseudo-Code: Making a PB and J Sandwich
