Question 1

Define Constructors

Answer 1

A constructor is a member function in a class that has the same name as its class. The constructor is automatically invoked whenever an object class is created. It constructs the values of data members while initializing the class.

Question 2

What is an object?

Answer 2

An object is an instance of a class through which we access the methods of that class. “New” keyword is used to create an object. A class that creates an object in memory will contain the information about the methods, variables, and behavior of that class.

Question 3

What is serialization

Answer 3

When we want to transport an object through a network, then we have to convert the object into a stream of bytes. The process of converting an object into a stream of bytes is called Serialization. For an object to be serializable, it should implement ISerialize Interface. De-serialization is the reverse process of creating an object from a stream of bytes.

Question 4

What are value type and reference types

Answer 4

A value type holds a data value within its own memory space
ex. int a = 30;

Reference type stores the address of the Object where the value is being stored. It is a pointer to another memory location.
ex. string b = “Hello”;
