I actually only program part time now as I am in semi-retirement (My full
time job for the last three years is as a teacher -- the hours are much
better and it is rewarding in ways other than financial). I still program
now in PHP for backend web work part time freelance.
I started today (first day of school) with an Algebra 2 class. We discussed
order of operations (PEMDAS). The question came up that we should do the
parentheses first before the brackets because they thought the brackets
should always be done last. I had to explain to them that IN MATH
parentheses, brackets and braces were all the same thing. In a programming
language they took on different meanings, although always enclosures.
The analogy here is simple. The three things are like case sensitivity. In
everyday language (analogy: MATH) they mean the same thing. However, in a
programming language they take on different meanings (analogy: VARIABLES,
METHODS, CONSTANTS).
Tony (I know you wrote this one Jerry), that is what you fail to see. They
are NOT the same thing as in everyday language. They are, in fact,
different things.
BTW Jerry, I have you both beat in years of programming. I date back to
1963 with Fortran IV.
