About C++ programming mcq oops concept

Q1. Explain oops concept, pillars of c++, differences
Ans. 
OOPs concept in C++ involves encapsulation, inheritance, polymorphism, and abstraction.
• Encapsulation: Bundling data and methods that operate on the data into a single unit (class). Example: class Car { private: int speed; public: void accelerate() { speed += 10; } };

• Inheritance: Allows a class to inherit properties and behavior from another class. Example: class ElectricCar : public Car { public: void chargeBattery() {...read more

Q2. Program on Queue, difference between structure and class
Ans. 
A queue is a data structure that follows the FIFO (First In First Out) principle. Structure and class are similar in C++, but classes have additional features like data hiding and inheritance.
• In C++, a structure is a user-defined data type that can hold different types of data. It is used to group related data together. Example: struct Queue { int front, rear; int capacity; int* array; };

• A class in C++ is similar to a ...read more
