Two constructors, which is default?

Question

Okay I got a pretty simple assignment.

I got these two constructors for class Person:

Person( const string &, const string &, const string &a         


        

Answer 1

If you ask which could be called; that depends on how you create object.

For example;

1 - First is called

Person person = new Person("a","b","c");

2 - Second is called

Person person = new Person("a","b","c","d");
