KENT RO Systems Product Management Trainee Interview Questions, Process, and Tips

C is a procedural language, C++ is an object-oriented language, and Java is a class-based object-oriented language.

• C is a procedural language used for system programming and embedded systems.

• C++ is an object-oriented language that extends C and adds features like classes, inheritance, and polymorphism.

• Java is a class-based object-oriented language that runs on a virtual machine and is used for web development and enter

Class is a blueprint for creating objects, while an object is an instance of a class.

• A class is a template or blueprint for creating objects

• An object is an instance of a class

• Classes define the properties and methods that objects will have

• Objects can interact with each other through their methods

• Example: Class - Car, Object - Honda Civic

OOPS stands for Object-Oriented Programming System. It is a programming paradigm based on the concept of objects.

• Encapsulation - bundling of data and methods that manipulate the data within a single unit

• Inheritance - ability of a class to inherit properties and characteristics from a parent class

• Polymorphism - ability of objects to take on multiple forms or behaviors

• Abstraction - ability to focus on essential features ...read more

Classes, arrays, and structures are all data structures used in programming.

• Classes are user-defined data types that encapsulate data and functions.

• Arrays are a collection of similar data types stored in contiguous memory locations.

• Structures are user-defined data types that group together variables of different data types.

• Classes and structures can have member functions, while arrays cannot.

• Arrays have a fixed size, w...read more

Function is a block of code that performs a specific task. Recursion is a technique of calling a function within itself.

• Functions are reusable code blocks that can be called multiple times with different inputs

• Recursion is useful for solving problems that can be broken down into smaller sub-problems

• Example of recursion: calculating factorial of a number

• Example of function: sorting an array of numbers

WAP to calculate factorial using recursion.

• Define a function that takes an integer as input

• Check if the input is 0 or 1, return 1 if true

• If input is greater than 1, call the function recursively with input-1

• Multiply the input with the result of the recursive call

• Return the result
