Class a
Class b

When i use a as a.static member of b i cannot access any of the method of class.a. Within b
Unresolved external

Post the code if you can that will help us to analyse

Apart from declaring a member static you have to define it outside the class. For example

struct A
{
   static int x; // it iis a declaration only
};

int A::x; // it is a definition 

[aclark17]

How would you call method
static void setx(int n){x=n;}

[vlad from moscow]

If it is indeed a static method then you can call it by using two different methods. Let assume that this method belongs to class A and a is an object of class A. Then you can write either

A::setx( value );

or

a.setx( value );

[Peter87]

class A
{
public:
	static void setx(int n){x=n;}
private:
	static int x;
};

int A::x;

int main()
{
	A::setx(7);
}

[aclark17]

Would a call to setx within the ctor of A change the value of x
A()
{
setx(2);
}

Yes, it will be changed.
