What does this mean "::"

[jinxjack]

for example :

String&&String :: operator = (const String & rhs)

What does this line mean? thank you.

:: shows what namespace you are using, For example:

namespace myNameSpace
{
int a;
int b;
}

myNameSpace::a = 12; // I am using a, which is in namespace myNameSpace 

class myClass
{
public:
    void myMethod();
};

void myClass::myMethod() // I am defining myMethod member of myClass class
{
..
}

Meaning it is a calling function. I did not understand the second part?

[jinxjack]

for example

class string
......
Public 
operator int();
operator char *();
};

string :: operator int()
{}

string :: operator char*()
{}

what does this whole program means?

I guess this

string :: operator int() 
{}

means that the string is changed into an integer and the result is returned. But I'm not sure...
