... null-terminated C-style string. To output the address, you can cast the char* to a void* (this can be done to any pointer variable). Figure 13.1 demonstrates printing a char* variable in both string and address formats. The address prints here as a hexadecimal (base-16) number—in general, the way addresses print is implementation dependent. To learn more about hexadecimal numbers, see Appendix D, Number Systems. We say more about controlling the bases of numbers in Section 13.6.1 and Section 13.7.4.
