Random internet people explaining math better then math teacher

there is no reason for a (non-foreach) for loop to be any more or less finite than a while loop.

for (a; b; c)
{
  d;
}

is just syntactic sugar for

{
  a;
  while (b)
  {
    d;
    c;
  }
}

in most or all languages with c-like syntax.
