Why does C insist on differentiating between "=" meaning assignment and "="
meaning equality test. People naturally write "A = B" and "if A = B...".
Based on the context the compiler should be able to figure out whether the
"=" sign refers to assignment or equality test. I know that C allows you
to do the assignment and then check the value of the assignment and that
this is often useful but it is IMO something that totally confuses me as a
novice C programmer.

I looks like you need a little look-ahead. Ada matches a "end" with a
"begin" but matches an "end if" with an "if" ("end case" with "case", "end
loop" with "loop", etc).
