Can a std::string contain embedded nulls?

Question

For regular C strings, a null character \'\\0\' signifies the end of data.

What about std::string, can I have a string with embedded null c

Answer 1

Yep this is valid.

You can have a null character in the middle of the string.

However, if you use a std::string with a null character in the middle with a c string function your in undefined behaviour town - and nobody wants to be there!!!:

 int n = strlen( strWithNullInMiddle.c_str() ); // Boom!!!
