Object1(int a, int b)
Object1(int a, int b, int c)
Object1(int a, int b, int c = NULL)
in the 1st case I am overloading a constructor - one takes 3 args and another takes 2 args.
In 2nd case I am writing only 1 constructor and initializing c by default to NULL and it will get initialized to what ever value is passed (if at all)
Is there any preferred method? Which one should I use when?
I am guessing that if one of the arguments in const I will have to overload only. Am I right?
