Cognizant Program Analyst Trainee Interview Questions, Process, and Tips

Polymorphism is the ability of an object to take on many forms.

• Polymorphism allows objects of different classes to be treated as if they are of the same class.

• It is achieved through method overriding and method overloading.

• Example: A shape class can have different subclasses like circle, square, and triangle, each with their own implementation of the draw method.

• Polymorphism makes code more flexible and reusable.

Abstraction is the process of hiding complex implementation details and showing only the necessary information to the user.

• Abstraction is a fundamental concept in object-oriented programming.

• It helps in reducing complexity and increasing efficiency.

• Abstraction can be achieved through abstract classes and interfaces.

• For example, a car dashboard is an abstraction of the car's internal workings.

• Another example is a TV rem...read more

Class is a blueprint for objects while interface defines a contract for classes to implement.

• A class can have attributes and methods while an interface only has method signatures.

• A class can be instantiated while an interface cannot.

• A class can only inherit from one class while it can implement multiple interfaces.

• Example: Class - Car, Interface - Drivable

• Car can have attributes like color, model, etc. while Drivable o

• DBMS manages data in files while RDBMS manages data in tables with relations.

• DBMS does not support client-server architecture while RDBMS supports client-server architecture.

• DBMS does not enforce any constraints while RDBMS enforces constrai...read more

OS manages hardware and software resources to provide a user-friendly interface for running applications.

• OS communicates with hardware components to manage resources like memory, CPU, and storage.

• It provides a user interface for running applications and manages input/output operations.

• Examples of OS include Windows, macOS, and Linux.

• OS also manages security and permissions for users and applications.

OOPs is a programming concept that relates real-life objects to classes and objects in code.

• Classes represent real-life objects and their properties and behaviors

• Objects are instances of classes and can interact with each other

• Inheritance allows for the creation of new classes based on existing ones

• Polymorphism allows for the same method to be used for different objects

• Encapsulation hides the complexity of the code fro

The frog will require 98 jumps to get out of the well.

• The frog jumps 2m high but falls down 1m, so it covers a net distance of 1m with each jump.

• To calculate the number of jumps, we need to subtract the initial jump of 2m from the total depth of the well (100m).

• The remaining distance to cover is 100m - 2m = 98m.

• Since the frog covers 1m with each jump, it will require 98 jumps to cover the remaining distance and reach t
