Given a vector<char> x with at least one element, you can write: &x[0]

With the newest C++ standard you can use x.data() to get a pointer to the data as well.

The data member function is also available.
std::vector::data - cppreference.com

You have to remember that unlike std::string::data(), std::vector::data() will not give you a sequence with null-character at the end.

std::string::data isn't guaranteed to either. Although enough programmers rely on it to anyway, so most implementations will. But properly, you should use std::string::c_str if you want a null terminated string.

I suggest you to reread the newest standard then. It IS guaranteed and both operations are equivalent.
