  1. Welcome to MDD310 Week 1 live lecture Monday January, 6th 2014 6:00 – 7:10 pm

  2. IPO charts What are they • IPO stands for input, processing, output • It is a chart to let you break down a problem into pieces that you can then use to develop psudeocode that will solve the problem • For web designers, this is the same as a storyboard but it solves a problem instead of showing the flow of a website.

  3. So how does it work • First you have to have a problem, let’s use something simple • Enter a name, hours worked each person gets paid $10 per hour, display gross pay.

  4. IPO chart • This is were you break down the problem into its 3 parts input, processing, output. Lets use a simple table to do this

  5. Results • As you can see this effectively breaks down the problem into small pieces that you can then use to create the pseudocode. • So what is pseudocode???

  6. Pseudocode • Pseudocode is a English like solution to a problem that is not tied to any computer language. • Pseudocode can contain some or all of the following items, variable names, math, decision statements. • Lets look at each component

  7. Variable names • Variable names are small names that represent content within the computer memory, for us let’s just think of them as identifiers for data that is entered, processed, or is display as results. • Example in our problem we are entering name and hours worked. So our variable names could be DOG – for name and PIG – for hours worked.

  8. Really?? • DOG and PIG would work but they make no sense when we read the names. • So lets us Name_in and HW_in notice these name no only make sense but they also tell us that the information is inputted • There are 2 other names we need for the problem, put some idea in the chat box.

  9. So Now what • Ok we have now have our variable names • Name_in, HW_in, GP_out • Now we are ready to make some pseudocode, lets look at out IPO chart again. We can see that the process is the next step so let’s build some pseudocode

  10. Pseudocode So let’s get started I use Display to show items on the screen, and input to get the values the users enter. • Start • Display “enter your name” • Input Name_in • Display “enter hours worked” • Input HW_in • GP_out = HW_in * 10 • Display Name_in • Display HW_in • Display “your gross pay is” GP_out • End

  11. So what does it mean • This pseudocode shows us the path we would need to take, to solve the problem. • Questions?? • Make sure to look at the lecture and the hints I will send out on Tuesday and Wednesday, for the skill builder assignments.

  12. Course Projectmilestone #1 • You have to start the process of rebuilding OtherStuff.com • Let's look at the original website • Link

  13. Milestone #1 You can see it is very plain website, you have to do the following for milestone #1 Logo – create a new log for the site must contain the phrase “stuff you don’t need but really want” Make sure you send it in as a .jpg Also create a small paragraph about the color scheme that you want to use in the new website. Here is a web site that might help you with that http://www.supportdash.com/color-tutorials-web-designers/

  14. Questions??
