It isn't correct, unfortunately :-(. "char name[40];" declares an array
with 40 elements, but as C++ uses zero based counting this gives valid
array elements name[0] through name[39]. name[40] is beyond the end of
the declared array. As Tom says, it's the 41st element.
You have just been lucky so far! I was writing one byte beyond the end
of a string in one of my programs due to a bug, and when I fixed it a
number of random corruptions and problems went away (fortunately none of
the customers entered full lines of text and so it hadn't provided any
on site problems).
