C doesn't encourage subroutines that have multiple entry and multiple
exit points. Pity.

Multiple exit points are no problem - you can easily

return;

from a function wherever you like.

Multiple entry points to a *function* are a bit more awkward - but you
can enter other types of block at multiple points. If you know C you
might enjoy this:

I's occurred to me, more than once, that C was invented to run on a
PDP-11, and that a $400 Dell has 10,000 times the memory and a
thousand times the speed of an 11. So why doesn't somebody invent a
language (and a methodology) that produces/forces reliable code and
requires less debugging, and does rudimentary stuff like data and code
separation, at some expense in runtime resources?

They have, of course - not many people use C to write applications for
desktop machines any more. They use C#, java, all sorts of other
languages and frameworks that do most or all of what you are asking.

However, to take up your analogy, todays microcontroller *is* similar
in power to a PDP-11, so C is now in fact quite a good fit!
