How to initialize structure data type using constructor? ( If you don't understand my question see description.)

Question

#include<iostream>
using namespace std;
class A {
private:
struct str {
int dd,mm,yy;
};
public:
A()
{

}
};
int main ()
{
A a;
}
//Is it possible or not?

Answer 1

Shadow But there is no constructor here? Is it possible to initialize using structure or not?

Answer 2

Right now you only have the inner struct, but not an instance of it you could initialize. The class 'A' needs to store an object of the struct as a member field, since the struct itself is only the blueprint. If you include that, then initializing the object is possible, sure. Here is an example:

Answer 3

There are two constructors in the outer class in my code, so if that is not what you want, then I don't quite understand your question. It would be helpful to me if you could clarify the following:
What do you want to initialize?
Where and how do you want to initialize it?
What do you want to initialize it with?
