Suppose I have class like
class A{
public:
A(int a, boost::shared_ptr<int> ptr){
// whatever!
}
};
My question is, what's the default value for that ptr? I'd like to be able to create an instance of that class using
A myA(5);
Sure I know I could create another constructor with just one parameter, but I'm looking for something like
A(int a, boost::shared_ptr<int> ptr = WAT?)
Is it possible? Currently I'm using the two-constructors way, but it would be great to do it this way.
#include <boost/make_shared.hpp>
A(int a, boost::shared_ptr<int> ptr = boost::make_shared<int>())
