Q1. Explain Basics OOP Pillars
Ans. 
The basics of OOP (Object-Oriented Programming) pillars are encapsulation, inheritance, and polymorphism.
• Encapsulation: Bundling data and methods together in a class to hide implementation details.

• Inheritance: Creating new classes from existing ones, inheriting their properties and behaviors.

• Polymorphism: Objects of different classes can be treated as objects of a common superclass, allowing flexibility and extensibili

Q2. What's copy constructor. Why it's passed by reference Why copy constructor can not be void
Ans. 
A copy constructor is a special constructor that creates a new object by copying the values of another object.
• Copy constructor is used to create a new object with the same values as an existing object.

• It is passed by reference to avoid unnecessary object copying, which can be expensive.

• Copy constructor cannot be void because it needs to return the newly created object.

Q3. Difference in array and linked list
Ans. 
Array is a contiguous block of memory, while linked list is a collection of nodes connected by pointers.
• Array has constant time access to elements, while linked list requires traversing the list.

• Array has fixed size, while linked list can dynamically grow or shrink.

• Insertion and deletion in array is expensive, while linked list can easily insert or delete nodes.

• Array is suitable for random access, while linked list is

Q4. Given three points how to check if they are colinear
Ans. 
To check if three points are colinear, calculate the slope between each pair of points and compare them.
• Calculate the slope between the first two points using the formula: slope = (y2 - y1) / (x2 - x1)

• Calculate the slope between the second and third points using the same formula

• If the slopes between all pairs of points are equal, then the points are colinear

Q5. Given point and circle how to find if point is inside circle or outside circle
Ans. 
To determine if a point is inside or outside a circle, calculate the distance between the point and the center of the circle.
• Calculate the distance between the point and the center of the circle using the distance formula: sqrt((x2 - x1)^2 + (y2 - y1)^2)

• If the distance is less than the radius of the circle, the point is inside the circle. If it is equal to the radius, the point is on the circle. Otherwise, it is outsid

Q6. How to find resultant of two vectors in terms of magnitude and direction
Ans. 
The resultant of two vectors can be found by adding the magnitudes and finding the direction using trigonometry.
• To find the magnitude of the resultant, use the Pythagorean theorem: magnitude = sqrt(a^2 + b^2)

• To find the direction of the resultant, use trigonometry: direction = atan(b/a)

• If the vectors are given in terms of their components, add the corresponding components to find the resultant

Q7. Can child class point points to base class?
Ans. 
Yes, a child class can point to a base class.
• In object-oriented programming, a child class can inherit from a base class and use its methods and properties.

• A child class can also override the methods of the base class to provide its own implementation.

• Polymorphism allows a child class object to be treated as a base class object, enabling it to point to the base class.

• This is useful for code reusability and creating a h

• Caused by excessive function calls or large local variables

• Can lead to stack overflow error

Q2. What are acsess specifiers
Ans. 
Access specifiers determine the level of access to classes, methods, and variables in object-oriented programming languages.
• Access specifiers include public, private, protected, and default.

• Public allows access from any other class.

• Private restricts access to only within the same class.

• Protected allows access within the same package and subclasses.

• Default (no specifier) restricts access to only within the same package.

Q3. What is class and object
Ans. 
A class is a blueprint for creating objects, while an object is an instance of a class.
• A class defines the properties and behaviors of objects.

• An object is a specific instance of a class.

• Objects can have their own unique values for properties defined in the class.

• Classes can be used to create multiple objects with similar characteristics.

• Example: Class 'Car' defines properties like 'color' and 'model', while an object

Q4. Expalin oops concepts?
Ans. 
OOPs concepts are fundamental principles of object-oriented programming, including inheritance, encapsulation, polymorphism, and abstraction.
• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex imple...read more
