You can declare 8-, 16-, 32-, or 64-bit integer variables by using the __intN type specifier, where N is 8, 16, 32, or 64.. The following example declares one variable for each of these types of sized integers: std::nullptr_t is the type of the null pointer literal, nullptr. It is a distinct type that is not itself a pointer type or a pointer to member type. Its values are null pointer constant (see NULL), and may be implicitly convertedto any pointer and pointer to member type. sizeof(std::nullptr_t) is equal to sizeof(void*).
