Types Of Relationships In Object Oriented Programming (OOPS)
OOP Concepts in C#: Code Examples and How to Create a Class Object oriented programming (OOP) is a programming structure where Inheritance is also an is-kind-of relationship. The next step is to right-click on your project within the solution explorer and click Add, then choose New Item. You'll. Consequently, the set of possible relationships is extremely large and it is difficult to obtain sufficient training examples for all possible relationships. Because of. An Interface is a Can-Do relationship. You can In your example (case 3), this means: If your class inherits from the other class, it is an "IS-A" relationship.

In addition, an object is an instance of a class. Furthermore, C offers full support for OOP including inheritance, encapsulation, abstraction, and polymorphism: Encapsulation is when a group of related methods, properties, and other members are treated as a single object.
Polymorphism is when each class implements the same methods in varying ways, but you can still have several classes that can be utilized interchangeably.
Abstraction is the process by which a developer hides everything other than the relevant data about an object in order to simplify and increase efficiency. What is an Object? Objects are instances of classes. In other words, an instance of a class is an object defined by that particular class. Creating a new instance, or an object, is called instantiation.

This is how you define a class: A class is made up of three things: A name Operations Attributes Objects are created from a class blueprint, which defines the data and behavior of all instances of that type. In Cvalue types refer to other data type variables while objects are reference types. Moreover, other value types are stored in the stack while objects are stored in the heap.
Keep in mind that everything in C is a class. An object is a section of memory that has been configured according to the class blueprint. Every instance, or object, of a particular class has access to several methods and properties of that class. Data Abstraction This provides essential features without describing any background details. Abstraction is important because it can hide unnecessary details from reference objects to names.
It is also necessary for the construction of programs. Instead of showing how an object is represented or how it works, it focuses on what an object does. Therefore, data abstraction is often used for managing large and complex programs.
Encapsulation This binds the member function and data member into a single class. This also allows for abstraction. Within OOP, encapsulation can be achieved through creating classes. By Alex on December 4th, last modified by Alex on December 2nd, Object composition In real-life, complex objects are often built from smaller, simpler objects.
For example, a car is built using a metal frame, an engine, some tires, a transmission, a steering wheel, and a large number of other parts. A personal computer is built from a CPU, a motherboard, some memory, etc… Even you are built from smaller parts: This process of building complex objects from simpler ones is called object composition. The complex object is sometimes called the whole, or the parent. The simpler object is often called the part, child, or component.
For this reason, structs and classes are sometimes referred to as composite types. This reduces complexity, and allows us to write code faster and with less errors because we can reuse code that has already been written, tested, and verified as working.
Types of object composition There are two basic subtypes of object composition: A note on terminology: Composition To qualify as a composition, an object and a part must have the following relationship:
