What is static function and static class?..

Answer / anthony michael

Static function and static variable does not below to single
instance of a class.

To access static functions we don't need instance of a class
instead it can be accessed using the class name followed by
::operator as:
[class_name::static_function() ]

Static Class is not possible in C++. But it can be done in
Managed C++

Static Class:
For Static Class we can't create Instances and It can only
hold Static member's.

Creating a static class is therefore much the same as
creating a class that contains only static members and a
private constructor. A private constructor prevents the
class from being instantiated.

If compilers don't check your pointers strictly,
you can also write code as below,

class A
{
//some static function code here
//never access non-static attributes here
static void callMe() {}
};

int main()
{
A * inst = NULL;
(*inst).callMe();
}
