Contact. Products | A constructor is used to initialize the state of an object. We can increase the efficiency in which information is shared across your organization, saving you time and money. c) No extra operator is needed for dereferencing of a reference A : Constructor has the same name as the class itself, C : Constructors are automatically called when an object is created. One of the disadvantages of pass-by reference is that the called function may inadvertently corrupt the callers data.

Constructor has the group of instructions that are performed at the time of object creation.

d) 4.

c) Object

d) Encapsulation.

Explanation: Objects of any class cannot be made a friend of any other or same class whereas functions, classes and operator functions can be made a friend. A Method is a grouping of instructions that returns a value upon its execution. d) A base class cannot have pointer objects.

a) A reference cannot be made null

(d) All of the above. Our goal is to minimize the heartache of choosing multiple vendors and to provide top notch service for the maintenance and expansion of your business. 0000008535 00000 n

In the object-oriented programming world, constructors play an important role. d) Virtual function.

At what point of time a variable comes into existence in memory is determined by its.

0000001185 00000 n Method calls play a critical role in invoking methods.

Answer: A

There are many differences between constructors and methods. Your email address will not be published.

They cannot return anything, even void (the object itself is the implicit return).Functions must be declared to return something, although it can be void.

Lets discuss some major differences between constructor and method.
