| class call to constructor class B and C inherits from A, class D inherit from B and C. A has a variable that is declared as public called count. D calls the non-default constructor of it's of the ancestor |

| it means that D passes an argument in its constructor calls to its ancestors. e.g: Code: class A
{
public:
int count;
A():count(0){} // <- default constructor (no arguments passed)
A(int _count):count(_count){} // <- non default constructor
};
class B : public A
{
B():A(){}
B(int _count):A(_count){}
};
class C : public A
{
C():A(){}
C(int _count):A(_count){}
};
class D : public B,public C
{
public:
D(): B(1), C(2) {}
}
