It is arguably off-topic to the discussion at hand, but I think you might be
thinking of something else (or maybe it was the case in an ancient version of C++)
because that does not appear to be case. If it were,

  for (int i ...) { ... }
  for (int i ...) { ... }

would have to trigger a redeclaration error, but that happens neither in C++ nor in C.
The variable is also inaccessible outside the loop.
