explicit istrstream(const char* s); explicit istrstream(char* s);
Effects: Initializes the base class with istream(&sb) and sb with strstreambuf(s, 0).
s shall designate the first element of an ntbs.
istrstream(const char* s, streamsize n); istrstream(char* s, streamsize n);
Effects: Initializes the base class with istream(&sb) and sb with strstreambuf(s, n).
s shall designate the first element of an array whose length is n elements, and n shall be greater than zero.
