Operator >> problems

Ok guys. I have a class String, and i need to put the operator >> in that class. so i do this:

istream & operator>>(istream &in,String &str)
{
char string[30];
in.getline(string,30,'\n');
str=string;
return in;
}

but when i do:

void main()
{
String x;
cin>>x;
}

i have this error
error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'String' (or there is no acceptable conversion)

why?? I have the operator << and it works with no problems. Any idea??

Did you make the operator>> a friend in your class?

That shouldn't matter here from the error he's getting.

He proly didn't include a declaration of the function before main.

Also, use int main not void main.

Ok ok, i put a declarition of the function before main and it don't give me errors, but when a want to read a string from the stdin, it just read one letter, for exeample i want to write My car is red, but when i write the M the program just read that letter and don't read the rest of the string....

What can be???

This code works, now compare and figure out where u r going wrong

Code:

#include <iostream>

class String
{
	char str[30];
public:
	String()
	{
		str[0] = 0;
	}

	friend std::istream& operator>>(std::istream& in, String &ob);
	friend std::ostream& operator<<(std::ostream& out, String &ob);
};

std::istream& operator>>(std::istream& in, String &ob)
{
	in.getline(ob.str,30,'\n');
	return in;
}
std::ostream& operator<<(std::ostream& out, String &ob)
{
	out << ob.str;
	return out;
}

int main()
{
	String s1;

	std::cin >> s1;
	std::cout << s1;

	return 0;
}
