Question

Which among the following best describes constructor overloading?

(a) Defining one constructor in each class of a program

(b) Defining more than one constructor in single class

(c) Defining more than one constructor in single class with different signature

(d) Defining destructor with each constructor

I got this question in a national level competition.

Query is from Overloading Constructors topic in portion Constructors and Destructors of Object Oriented Programming

Answer 1

Right answer is (c) Defining more than one constructor in single class with different signature

For explanation: If more than one constructors are defined in a class with same signature, then that results in error. The signatures must be different. So that the constructors can be differentiated.
