What's a program? Operating system?

What's a framework?

• something that makes it faster to build an application because it contains most of the things you would commonly write

Workflow - how do you write a program?

• Learn about customer's requirements -> translate to "stories"
• Pick a story that seems doable and start writing code that does it
• Show your work to the customer, get feedback
• Based on feedback, adjust stories (customer's "up front" requirements vs. changes once they see something working)
• Once story is finished, go back to "pick a story"...keep going until you're done! (This is an example of looping!)

alternate programming intro

Basic programming structures - or, how to do the "start writing code" step

• variables - words that hold information
• types of information - text, numbers, collections
• operators - doing stuff with variables
• loops - doing the same action a bunch of times
• printing - to the screen, or to a file

Writing a simple program

• opening the editor
• opening the command line
• adding two numbers together, storing in a variable
• printing variable to the screen
• save and run
