The one I particularly hate, which distresses me greatly, is the C++-ish
ability to declare a variable anywhere. E.g.,
foo() {
int i;
printf ("i = %d\n", i);
int j;
printf ("j = %d, i still = %d\n", j, i);
}
This is useful in exactly one situation that I can think of:
for (int i = 0; i < 100; i++) {
printf ("i = %d\n", i);
}
but even that has complications. (How do you declare multiple variables of
different types?)
It's not as if any existing code truly uses this -- the only code that has
this is C++, and C++ is not C. It adds very little to the language, except
for an ability to have even more badly written code, and will make some
compilers a bit harder to write (but that's balanced by making others a bit
easier to write).
It's ugly. Yuck.
