Cognizant Programmer Analyst Trainee Interview Questions and Answers
231 Interview questions
OOPs concepts include encapsulation, inheritance, polymorphism, and abstraction, essential for modular programming.
Encapsulation: Bundling data and methods in a class. Example: A 'Car' class with properties like 'color' and methods like 'drive()'.
Inheritance: Deriving new classes from existing ones. Example: 'ElectricCar' inherits from 'Car', adding features like 'batteryCapacity'.
Polymorphism: Ability to use a si...
Web development involves creating and maintaining websites through various stages, including planning, design, coding, and testing.
1. Planning: Define the website's purpose and target audience. Example: A portfolio site for showcasing work.
2. Design: Create wireframes and mockups to visualize layout. Example: Using tools like Figma or Adobe XD.
3. Development: Write code using languages like HTML, CSS, and JavaScri...
Inheritance is a fundamental OOP concept allowing a class to inherit properties and methods from another class, promoting code reuse.
Base Class: The class from which properties and methods are inherited is called the base class (or parent class). For example, 'Animal' can be a base class.
Derived Class: The class that inherits from the base class is called the derived class (or child class). For instance, 'Dog' can...
A leap year occurs every four years, except for years divisible by 100 but not by 400, ensuring calendar accuracy.
Basic Rule: A year is a leap year if it is divisible by 4.
Century Exception: Years divisible by 100 are not leap years unless they are also divisible by 400.
Examples: 2020 is a leap year (divisible by 4), while 1900 is not (divisible by 100 but not by 400).
Correct Calculation: To check if 2000 is a lea...
What people are saying about Cognizant
Polymorphism allows objects to be treated as instances of their parent class, enabling method overriding and dynamic method resolution.
Method Overriding: A subclass can provide a specific implementation of a method that is already defined in its superclass. Example: A class 'Animal' with a method 'sound()', and subclasses 'Dog' and 'Cat' overriding 'sound()' to bark and meow respectively.
Method Overloading: Multip...
Public, private, and hybrid clouds differ in ownership, accessibility, and deployment models, catering to various business needs.
Public Cloud: Services offered over the internet, accessible to anyone (e.g., AWS, Google Cloud).
Private Cloud: Exclusive cloud infrastructure for a single organization, enhancing security and control (e.g., VMware, OpenStack).
Hybrid Cloud: Combines public and private clouds, allowing da...
Python is my preferred language due to its simplicity, versatility, and strong community support, making it ideal for various projects.
Easy to learn and read: Python's syntax is clear and concise, making it accessible for beginners. For example, a simple 'print' statement is intuitive.
Versatile applications: Python is used in web development (Django, Flask), data analysis (Pandas, NumPy), and machine learning (Ten...
Data types define the kind of data a variable can hold, influencing operations and memory usage.
Primitive data types include integers, floats, and characters. Example: int age = 25;
Composite data types include arrays and structures. Example: int numbers[] = {1, 2, 3};
Data types help in memory allocation and type checking during compilation.
Different programming languages have different data types. Example: Python ...
AD domain server is a server that manages user accounts and permissions within a Windows Active Directory domain.
AD domain server stores user account information such as usernames, passwords, and group memberships.
It authenticates and authorizes users to access resources within the domain.
It allows for centralized management of network resources and security policies.
Examples: Windows Server, Active Directory Doma...
0 and 1 are integers and their data type is typically 'int' in programming languages.
Data type of 0 and 1 is 'int' in most programming languages like C, C++, Java, etc.
In some languages like Python, 0 and 1 are considered as 'bool' type for boolean values.
In SQL, 0 and 1 can be used as values for boolean data types like 'BIT'.

Tuples are immutable and ordered collections, while lists are mutable and ordered collections in Python.

Tuples are immutable, meaning their elements cannot be changed once assigned, while lists are mutable and can be modified
Tuples are faster than lists for accessing elements, but lists are more flexible for operations like adding o...
