OOPs concepts in C#, SOLID and design principles, Task vs Thread, Interface vs Abstract class

• OOPs concepts in C# include encapsulation, inheritance, polymorphism, and abstraction

• SOLID principles are Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion

• Task is a unit of work in C# that represents an asynchronous operation, while Thread is a separate path of execution wi...read more

Python is a high-level, interpreted programming language with dynamic semantics.

• Python has several built-in data types including integers, floats, strings, booleans, and complex numbers.

• It also has built-in data structures like lists, tuples, and dictionaries.

• Python supports object-oriented programming and has a rich standard library.

• Examples: x = 5 (integer), y = 3.14 (float), z = 'hello' (string), a = True (boolean),...read more

Logic building/thinking is the process of analyzing and solving problems using reasoning and critical thinking skills.

• It involves breaking down complex problems into smaller, more manageable parts

• Identifying patterns and relationships between different pieces of information

• Using deductive and inductive reasoning to draw conclusions

• Applying logical principles to solve problems in various fields such as computer programm...read more

Copy constructor is a special type of constructor which creates a new object as a copy of an existing object.

• Copy constructor is used to initialize a new object as a copy of an existing object.

• It takes an object of the same class as a parameter.

• It is called automatically when a new object is created from an existing object.

• Example: class MyClass { public: MyClass(const MyClass& obj) { // copy constructor logic } };

Copy constructor is used to create a new object as a copy of an existing object, while assignment operator is used to assign values from one object to another.

• Copy constructor is called when a new object is created from an existing object, while assignment operator is called when an existing object is assigned values from another object.

• Copy constructor creates a new object with its own memory space, while assignment o...read more

A static function is a function that is associated with a class rather than an instance of the class.

• Static functions can be called without creating an instance of the class.

• Static functions are commonly used for utility functions that do not require access to instance-specific data.

• Static functions are declared using the 'static' keyword in many programming languages.

• Example: 'Math.max()' in JavaScript is a static fun

Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.

• Start with 0 and 1 as the first two numbers in the series

• Add the previous two numbers to get the next number in the series

• Repeat this process to generate the Fibonacci series

Singleton design pattern ensures a class has only one instance and provides a global point of access to it.

• Ensures a class has only one instance

• Provides a global point of access to that instance

• Commonly used in scenarios where only one instance of a class is needed, such as database connections or logging

Types of polymorphism include compile-time polymorphism (method overloading) and runtime polymorphism (method overriding).

• Compile-time polymorphism is achieved through method overloading, where multiple methods have the same name but different parameters.

• Runtime polymorphism is achieved through method overriding, where a subclass provides a specific implementation of a method that is already defined in its superclass.
