Null character and string object

Hi folks,

Just a quick question: what is so illegal about the following line of code? That is, why would it throw an exception?

Code:

---

std::string someStr='\0';

---

If I define someStr first, and then assign the null character second, I have no problem. Why is this? Aren't the two equivalent, but I've just shifted the assignment down a bit?

Thanks,

You can't initialise an std::string with a character in that way. If you really need to you should be able to do the following:

std::string someStr(1,'\0');

Note that in C++ initialisation and assignment are two very different things.

The assignment operator is overloaded to receive a string as parameter. Is like having a function:
void f(char *str);
and use it passing a char.

Omnius: Thankyou, what you told me coupled with a bit of research of my own answered my question.

gustavosserra: That's true, but after reading the definition for std::string I found that it's also overloaded for char, which would explain why I had no problems assigning the character later.

Thanks for the help, both of you. Much appreciated.
