default on class' public data

[baray98]

My class has a method that takes a class ( data class) as parameter and I want to put a default value if the caller won't supply it like

class::function(int a = 3);

class::function(int a = 3);

To copy to clipboard, switch view to plain text mode 

kinda thing.

so here's what i did

class A
{
   public:
     class B
     {
       int x;
     };
     A()
     { defaultB.x = 3};
     run(B options = defaultB); // compiler complains about non-static defaultB which is correct
     private:
        B defaultB;
};

class A
{
   public:
     class B
     {
       int x;
     };
     A()
     { defaultB.x = 3};
     run(B options = defaultB); // compiler complains about non-static defaultB which is correct
     private:
        B defaultB;
};

do you guys know of any way that i can implement default on my methods passing a class ?

Make defaultB a static object or construct defaultB inside the constructor or provide a constructor for B that will create defaultB and call that constructor as the default parameter for the method from A.

I did the assigning of defaults in my constructor
