Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Inheritance allows a child class to override a method from its parent class, providing different func

Constructors are special methods in a class that are used to initialize objects of that class.
Constructors have the same name as the class they belong to.
They are called automatically when an object is created.
Constructors can have parameters to initialize object properties.
Example: public class Car { public Car(String color) { this.color = color; }}
Design patterns in C++ are reusable solutions to common problems in software design.
Design patterns help in creating flexible, maintainable, and scalable code.
Examples of design patterns in C++ include Singleton, Factory, Observer, and Strategy.
Each design pattern has its own purpose and can be applied in different scenarios.
Understanding design patterns can improve code quality and efficiency.

Virtual DOM is a lightweight copy of the actual DOM in React, used for efficient updates.
Virtual DOM is a concept where a lightweight copy of the actual DOM is created in memory.
React uses the virtual DOM to efficiently update the actual DOM when there are changes in the application.
When changes are made to the virtual DOM, React calculates the most efficient way to update the actual DOM, minimizing performance impact.

Embedded systems are specialized computing systems designed to perform specific tasks within a larger system.
Embedded systems are typically found in everyday devices such as smartphones, cars, and household appliances.
They are designed to be efficient, reliable, and often operate in real-time.
Embedded systems often have limited resources such as memory and processing power.
Examples of embedded systems include microcont...
Deadlocks are situations in which two or more processes are unable to proceed because each is waiting for the other to release a resource.
Deadlocks occur in multitasking environments where processes compete for limited resources.
Four conditions must hold for a deadlock to occur: mutual exclusion, hold and wait, no preemption, and circular wait.
Example: Process A holds Resource 1 and waits for Resource 2, while Process ...
