A good programming language is expressive. That means I can easily turn the thoughts of my head into code. A good programming language is easy to read. It's important for code to be read because code lives. Others edit it, extend it, learn from it. A good programming language is fast.
A programming language is a language written for a computer. The instructions control a computer's actions. So what can a computer do
- Get Information This is called input. A computer can get information though a keyboard, mouse, microphone, video camera, internet, etc.
- Send Information This is called output. A computer can send information through the screen, speakers, the internet, etc.
- Manipulate Information A computer can add, subtract, etc. It can use that same math to manipulate images, video, audio, text files.
- Store Information A computer can store information. It can store videos, images, text, and programs. The computer stores these things in what's called memory.
- Execute Information This is the magical part of computers. Computer instructions called code can be stored in the memory, just like images and video are stored in the memory. The computer can execute parts of it's own memory to get, send, manipulate, store and even execute information.
..to be continued.. talk about how memory is stored in a big long list. Maybe talk about operating systems
...discuss functions etc
What does the . mean in obj.param
Do the variable names exist in memory? Or are they turned into indexes at compile time? Or is only the variable type used at runtime (polymorphism)?
