Question Strings C++
By PeterNaut, 9 years ago, In English

Do strings in c++ always end with null? If I have a string str = "hey";, will str[3] always be null? I only care about the index following the last character of the string, that is, I don't care what the value for str[4] is. :P

string s = "hey";
if (s[3] == NULL)
    cout << "ok";

output: ok

"If pos is equal to the string length, the function returns a reference to a null character ('\0')." It's posted here.
