Technical Questions
What are pointers?
A pointer is a variable that stores the address of other variable of the specified data type. They point to locations in memory.
What is the difference between near, far, and huge pointers?
Near Pointer is used to store the address, which has a maximum size of 16 bits.
Syntax:
<data type> near <pointer definition>
Far Pointer is typically considered to be a pointer with a 32-bit size.
Syntax:
<data type> near <pointer definition>
Huge pointers also have the same size as 32 bits, but they can also access bits stored outside a segment.
What is the difference in the use of char type versus the varchar type?
Char is used when we need to store the data of smaller size and actual size, whereas Varchar is used when we need to store data of variable lengths such as the name of the person or place. Char is more space efficient than Varchar.
What do you mean by Recursion Function?
In a recursive function, the function calls itself a defined number of times.
Compare NumPy Array and List in Python.
NumPy Array | Python List |
It supports similar data types and demands low
memory |
It supports different data types and demands large
memory |
It is homogenous and faster compared to the NumPy array | It is homogeneous as well as heterogeneous and is slow |
What is Abstract class?
An abstract class is a template definition of methods and variables in a specific class, or category of objects. A class can be made into an abstract class using the keyword ‘abstract.’ These classes contain one or more abstracted behaviour or methods.
How are this() and super() methods used with a constructor?
this() and super() are used to call a constructor. The this() method is used to call the constructor of the current class, whereas the super() method is used to call the constructor of the parent class.
What is the difference between union and anonymous union.
A union is a user-defined data type which enables the declaration of different kinds of variables.
Anonymous Union is a special type of union with no name. Since they do not have names, they have some restrictions. They cannot have member functions and static data members. All their data members must be public.
What do you mean by the Volatile Variable?
The volatile variable is a variable that can be changed by operating systems or other software. This is the variable used to end a loop or a thread. We can read/ write volatile variables from/to main memory. They are not usually cached in temporary memory devices. We can use the volatile variable in programming languages such as C, C++, and Java.
Differentiate Stack with Queue in Data Structures?
The main difference between stack and queue lies in their arrangement of data elements. Stack follows a Last In, First Out arrangement where the last entered data is processed first. Queue, on the other hand, follows a First In, First Out arrangement, meaning the first entered data is processed first.
When can we use the data types such as VARCHAR, CHAR, and VARCHAR (MAX)?
When data has a variable length, we can use data types such as VARCHAR as well as VARCHAR (MAX). VARCHAR data type employs dynamic memory location. It could be a letter, number, or character.
When data has a defined length, CHAR data type can be used. It uses a static memory location.
Explain WYSIWYG.
WYSIWYG, which stands for What You See Is What You Get, is an editing software used to edit the content. It enables users to manipulate the content or layout without having to type any commands. Microsoft Word is a common example for a WYSIWYG editor.
What is Spiral Model in SDLC?
The spiral model combines the iterative development process with the waterfall model. With this model, we can avoid risks that may arise in different stages of software development. We can use the spiral model to generate better outcomes for large and complex software development projects.

}
}
public static void main(String args[])
{
int count=15;
//printing 0 and 1
System.out.print("Fibonacci Series: " + n1+" "+n2);
