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 Can’t Write a
Program?
You could write an algorithm…
