I think the OP means std::string, which also is not
zero-terminated. (On the other hand, C strings are
zero-terminated.)
You can obtain a 0 terminated "const char*" from an std::string
in 0(1) using c_str.
While the C++98 standard doesn't mandate it, the above
requirement means that 99% of string implementations are using
arraysinternally. The C++11 standard *does* mandate that the
implementation use arrays internally. So that means you can get a
valid char* from &myString[0].
That string will not be 0 terminated, but all the major compiler
providers (AFAIK) make that guarantee as an extension.
