So, what is Pseudocode? Essentially, it is an informal computer language. You write down a
computer program in a language that resembles plain English. Importantly, it should make sense to
you, the programmer (and hopefully other people as well). Later, when you are happy your
program will work, you translate it into an actual computer language on the computer.
Here's an example:
INPUT A
INPUT B
LET C = A + B
PRINT C
Now before we dissect this first example, let's define one important key term.
KEY TERM: Variable
A variable in computing is similar to what you may have learned in algebra. It's a letter, or even a
whole world, that stands for something. We could say C = 5, which would mean the variable C now
has the value of 5. Or we could say MENUITEM = Passwords, which would mean the variable
MENUITEM now has the value "Passwords".
The key term variable implies that a variable's value can change. So later in the program we could
set C = 7. So the variable C would then have the value 7, and so on.
