see these class:
class test
{
public:
void Created(){};
test()
{
Created();
}
};
now we can create objects from it. ok.
but can i overloading the scope-resolution ('::') for the object accept and change the Created() function?
No you can not overload ::. Why would you want to?
for change the functions(with diferente objects) outside of functions\class and others.
(in my case) the problem of class direved from other class is that i must re-declare the functions
You'd have to redeclare the function even if you could overload ::, so what's the problem?
class test
{
public:
virtual void Created() {cout << "Hello from test class\n";}
test()
{
Created();
}
};
class Child : public text
{
public:
virtual void Created() {cout << "Hello from Child\n";}
};
int main()
{
Child c;
c.Created(); // call Created in Child class
c.test::Created(); // call Created in test class
}
some day ago i read something, so please correct me.
i understand that i can't use a varname outside the functions\class's with '::' operator, but seems that i can use with static functions, can you explain please?
Can you post an example of the situation you're asking about?
i understand that i can't use a varname outside the functions\class's with '::' operator
Make the variable static and you can use it outside the class with :: opertor.
class MyClass
{
public:
static int x;
};
int MyClass::x = 0; // static variables must also be declared like globals
int main()
{
MyClass::x = 1;
}
the same for functions, right?
Functions are coded as normal.
class MyClass
{
public:
static int x;
static int foo();
};
int MyClass::x = 0; // static variables must also be declared like globals
int MyClass::fo()
{
return x;
}
int main()
{
MyClass::x = 1;
}
thanks...
for finish: can i do object polymorphism and use '::' operator?
Not that I know of.
