-
Which of the following statements are correct about constructors in C#.NET?

A.
func() is a valid overloaded function. |
|
B.
Overloading works only in case of subroutines and not in case of functions. |
|
C.
func() cannot be considered overloaded because: return value cannot be used to distinguish between two overloaded functions. |
|
D.
The call to i = s1.func() will assign 1 to i. |
|
E.
The call j = s1.func() will assign 2.4 to j. |
|
A.
If we provide a one-argument constructor then the compiler still provides a zero-argument constructor.
|
|
B.
Static constructors can use optional arguments.
|
|
C.
Overloaded constructors cannot use optional arguments.
|
|
D.
If we do not provide a constructor, then the compiler provides a zero-argument constructor.
