10+ MakeMyTrip Interview Questions and Answers

Inheritance is important in programming as it allows for code reuse, promotes modularity, and enables polymorphism.

• Inheritance allows us to create new classes that inherit the properties and methods of existing classes.

• It promotes code reuse by allowing us to define common attributes and behaviors in a base class and extend it in derived classes.

• Inheritance promotes modularity as it allows us to organize classes into a hierarchy, making the code more manageable and maintainab...read more

The interview questions cover topics like Python, list comprehension, XML, JSON, format specifiers in C, intents in projects, use of GitHub, GSM messaging, and Bootstrap.

• Python is chosen for its simplicity and readability, used in a project for data analysis.

• List comprehension is a concise way to create lists in Python, like [x for x in range(10) if x%2==0].

• XML is a markup language for storing and transporting data.

• JSON is a lightweight data interchange format, similar to HTM...read more

Object oriented programming is a programming paradigm that focuses on objects and their interactions.

• Objects are instances of classes that encapsulate data and behavior.

• Inheritance allows classes to inherit properties and methods from parent classes.

• Polymorphism allows objects to take on multiple forms and behave differently based on context.

• Encapsulation hides the implementation details of an object and only exposes a public interface.

• Examples of object oriented programming ...read more

Code to determine if a number is odd or even without using modulus operator.

• Use bitwise AND operator with 1 to check if the last bit is 0 or 1

• If the result is 0, the number is even, else it is odd

GDP stands for Gross Domestic Product, which is the total value of goods and services produced in a country in a given period.

• GDP is a measure of a country's economic performance.

• It includes all final goods and services produced within a country's borders.

• Other examples include recommendation algorithms on streaming services and voice recognition technology in car...read more

Polymorphism is the ability of an object to take on many forms. Inheritance is the mechanism of deriving new classes from existing ones.

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

• Inheritance allows a class to inherit properties and methods from another class.

• Polymorphism and inheritance are key concepts in object-oriented programming.

• Example of polymorphism: a shape class with different subclasses like circle, squa...read more

Cut pizza into 8 pieces in 3 strokes

• Make two perpendicular cuts through the center of the pizza to get 4 equal pieces

• Make a third cut through the center of one of the 4 pieces to get 8 equal pieces

• Ensure the cuts intersect at the center of the pizza for even slices

An operating system is a software that manages computer hardware and software resources.

• It acts as an interface between the user and the computer hardware.

• It provides services such as memory management, process management, and device management.

• Examples include Windows, macOS, Linux, and Android.

• It allows multiple applications to run simultaneously.

• It provides security features such as user authentication and access control.

Deadlock is a situation where two or more processes are unable to proceed because they are waiting for each other to release resources.

• Deadlock occurs when two or more processes are blocked and unable to continue executing.

• It happens when each process is holding a resource and waiting for another resource held by another process.

• Deadlock can be prevented by using techniques like resource allocation graph and banker's algorithm.

• Examples of resources that can cause deadlock inc...read more
