How big was it 30 years ago? In my opinion, tiny
compared to C.
30 years ago OK, however history doesn't stop in 1990. When I
visited University in the 70ths almost all academics used fortran, no matter if physics,
mathematics, economics, or even social sciences. So I was forced to learn in fortran IV.
Outside the academic biotope you had to learn cobol, because almost all development of
business applications used this cruel language even in 1990. For me C was a redemption
given me the chance to express myself. I'm now retired and can do whatever I want to
do. Hence I left behind c++, java, still using C beside golang and lots of shell
scripting.
