      Why don’t we append a terminating null at the end of any array and not just char[]?


    • #51020

      Null termination works for strings because there is a tightly defined encoding set, be it ASCII, Unicode or whatever. Simply put, a char is an integral type which has one state which is conveniently the empty character. When inspecting a null-terminated int array. We know we have hit the end of the array when we encounter an int object which stores a zero.

      This works until you want to store a zero somewhere in your array.

      You can’t disambiguate a “valid zero” from an “end of array zero,” at least you can’t with a simple integer type.
