C, STL, primitive languages that live on and on ... Re: Does anyone here know Siemens STL?

There are a lot of smart people here with wide ranging experiences, so
I like to ask questions from time to time that get more to philosophy.
So "If C is so evil why is it so successful" was one of those
questions.

The answer I see is that it is the path of least resistance to the
most successful outcome in the time horizon of the effort.

Or, it gets the job done.

Personally, I am stuck in the machine control world where things like
symbolic names and type checking are sometimes non-existant. And I
wonder why.

I am familiar with STL (and some of the others). My question was not
for help. I was trying to present a contrast between the nit-picking
the list was doing about C and that fact that a huge amount of mission
critical programming is done in languages that are essentially machine
code.

It was a ham fisted attempt. Don't post after too many high ABV IPA's.

Probably for the same reason that PZD is process data.
