In C, subtracting two pointers that point to elements of the same array yields a result of type ________.

  • double
  • int
  • ptrdiff_t
  • size_t
In C, subtracting two pointers that point to elements of the same array yields a result of type ptrdiff_t. This type represents the signed integral difference between the two pointers. It's important to use ptrdiff_t when performing pointer subtraction to ensure portability and accurate results, especially in situations involving pointer arithmetic.
