Not to mention BASIC
Both of which predate C

Guido was probably influenced by the ALGOL language stream, which used "for"
and "if". ALGOL 60 was a joint American and European effort and was significant
in the late 50s and 60's.
Guido's fellow countryman, Edsgar Dijkstra, took this publication language (the
ALGOL60 version) and produced a compiler for it. (It was not the first, but was
very early on). Then B. Randell and L.J. Russell visited him, learnt from his
experiences and returned to the UK to produce the KDF9 Whetstone ALGOL60
Compiler. Their book "ALGOL 60 Implementation" was a very early and influential
book in the field and occupies a significant place in the history of computing.
Computer language designers, including Nicholas Wirth (Pascal, Modula, Oberon),
have been influenced by ALGOL.
Sadly, "C" and its ilk, come from a totally different stream of language
development beginning with the likes of "CPL", "BCPL", "B" and developing into
"C" and "C++". This stream was originally focussed on language portability and
performance. This stream was much closer to the assembler language end of the
language spectrum, whereas the other stream was heavily biased towards
publication and later teaching.
I could say more but will restrain myself.

FWIW "++" reeks of assembler language notation.
The KDF9 Whetstone ALGOL60 Compiler was the one I used at Whetstone for
1-Dimensional Transient Heat-Flow calculations and Steam-Table generation. Our
course on it was 2.5 days long. We had wonderful training by English Electric,
Kidsgrove staff. I hate to think how long the same course would be now, a
month?
