Because, the only ioperator available is:
basic_ostream& operator<<(const void* p);
Which writes the pointer value (like %#p in printf).
The string version is the free function:
template
basic_ostream& operator<<(basic_ostream&
out,
const char* s);
// ... other templates cf. 27.6.2.5.4 of the standard
Which computes the length and inserts the string into the stream.
AFAIK there are no corresponding function in the std::ostream
interface (for formated output).
