And here I was sitting, thinking they all originated with Algol?
They did, of course; Algol after all is the first block structured language, and most
block structured languages since then copied its approach to name and data scope. (Not
all; for example, Python has scope rules that are noticeably different.)
Then there was Algol 68, which in spite of its name is not all that close to Algol 60. It
added a number of innovations that subsequently were adopted by C++. The iostreams
mechanism is a rather obvious example (I believe Stroustrup points out the Algol 68
heritage explicitly in one of his books).

Its history is deeper than that. Its part of a family of bracketed languages that started
with BCPL which became "B" and then "C". BCPL was written for the

we're coding in a
language that was developed for a PDP-11 minicomputer.
Developed for the PDP-7, actually. Contrary to popular belief, the "++" and
"--" operators were NOT the result of the PDP-11 addressing modes.
