What is Programming?
Programming is the ability to talk to the
computer in a language it can understand and
using grammar and syntax that it can follow to
get it to perform useful tasks for you. You write
code and the computer interprets your request and
does something. The code must be correct and
unambiguous.

Why so Many Programming Languages?
The code you type in is not the code that the
computer understands. A program converts the code
from text into a certain type of language that
the computer can decipher. What is that language
(think back to the fifth week of class)?

What if you Cant Write a Program?
You could write an algorithm
