C++ Classes

I was going through some old notes the other day, and found the following in my notes from undergraduate Operating Systems class, circa 1988, when I was first learning C++. To the tune of ZZ Top's "Cheap Sunglasses":

Got a programming assignment
And ya gotta do it right
If you write procedurally
It's gonna take all night

[chorus]:
It's not that hard
So just push up your glasses
And write yourself some C++ classes

Term project for OS
And grades are never free
You got a whole bunch of objects
Ya gotta treat homogeneously

[chorus]:
It's not too slow
It compiles in two passes
So just code up some C++ classes
