const X* const p suggests “p is often a const pointer to an X that is const”: you could’t alter the pointer p
That is solely symmetric with pointers to const, such as the undeniable fact that the compiler does all of the checking at compile-time, which means const doesn’t slow down your software additional resources and doesn’t involve you to write excess test-conditions to examine issues at runtime.
Extra multi-byte encoded people may be used in string literals, but they don't seem to be entirely portable. The most up-to-date C common (C11) permits multi-countrywide Unicode figures being embedded portably in C source textual content by utilizing uXXXX or UXXXXXXXX encoding (in which the X denotes a hexadecimal character), although this feature isn't yet greatly carried out.
