Answer 1

char/unsigned char types are an equivalent of byte in Java or other languages.

std::string has method c_str(), which returns char* with the length of std::string::size(). char*, being a c-string, can be considered as a full and complete binary representation of the underlying string.

Basically,

std::string s;

const char* s_data = s.c_str();
// do what you want with s_data

If all you want is an access to characters, using operator[] is enough:

char p = s[i]; // process that p as you want!

Information, provided here, should be enough for any kind of interaction with strings.
