关于C++字符串的问题，求任何比我厉害的人进入

    C++中的字符串末尾有'\0'，吗？？？

应该没有吧，要不c_str()这个函数用来做什么

楼上同学，字符串字面值可跟C++的字符串类型不一样的哦。
"hello"这样用双引号括起来的叫作字符串字面值。
字符串类型是用string类型来定义的，比如string s="hello"; s是一个字符串。

ps：查了下，string类型应该是有'\0'来结尾的。
另外附上一个以前的帖子

string::c_str
Generates a null-terminated sequence of characters (c-string) with the same content as the string object and returns it as a pointer to an array of characters.
A terminating null character is automatically appended.

string::data
Returns a pointer to an array of characters with the same content as the string.
Notice that no terminating null character is appended

The null character ' \0 ' is used as a special character in a C-string to mark the end of the string but has no special meaning in an object of type string
