"The STL features rather heavily a type named `std::size_t`, which by design is able to store the maximum size of a theoretically possible object of any type (including array). On most (all?) systems `std::size_t` is an alias to an `unsigned long`. More may be found about this type on [CppReference](https://en.cppreference.com/w/cpp/types/size_t). The equivalent counter part for signed integers is the [`std::ptrdiff_t`](https://en.cppreference.com/w/cpp/types/ptrdiff_t), which is the signed integer type of the result of subtracting two pointers. \n",
