Default Constructor

[Mauro Trevigno]

Hi People,

What class has a default constructor?

class Test { } // This one is consideres as a Default constructor or parameterless constructor ?

class Test1 { Test1() {} } // Default constructor - I think this one is the only Default constructor, right?

class Test2 {Test2 (int t){} } // A constructor with one parameter

Thanks.

Your first class has default constructor.

The "default constructor" is the one automatically inserted by the compiler if you don't provide one yourself. So it's the first example. The second is a parameterless (or no-arg) constructor, but because you've provided it it isn't considered a default one.

The default constructor is inserted by the compiler if you do not provide any constructor yourself.
