What is solid principle in software development?
It is an acronym for five design principles intended to make software designs more understandable, flexible and maintainable. Another benefit of SOLID principle is that it will make the code easier to read and understand, thus spending less time figuring out what it does and spend more time actually developing the solution.
What are solid design principles in OOP?
SOLID Design Principles E.. In Object Oriented Programming (OOP), SOLID is an acronym, introduced by Michael Feathers, for five design principles used to make software design more understandable, flexible, and maintainable.

What is the purpose of SOLID design principles in C#?
The SOLID Design Principles in C# are the design principles that help us to solve most of the software design problems. These design principles provide us with multiple ways to move the tightly coupled code between the software components which makes the software designs more understandable, flexible, and maintainable.
What is SOLID principles in C# Interview Questions?
SOLID principles are a set of design principles that are useful for creating complex yet comprehensible, dynamic and maintainable software in object-oriented software development.
Why are SOLID principles important?
The goal of the SOLID principles is to reduce dependencies so that we can change one area of software without impacting others. Additionally, they're intended to make designs easier to understand, maintain, and extend.
What does SOLID stand for?
SOLID is an acronym that stands for five key design principles: single responsibility principle, open-closed principle, Liskov substitution principle, interface segregation principle, and dependency inversion principle. All five are commonly used by software engineers and provide some important benefits for developers.
What is Design Patterns in C#?
Design Patterns in the object-oriented world is a reusable solution to common software design problems that occur repeatedly in real-world application development. It is a template or description of how to solve problems that can be used in many situations. "A pattern is a recurring solution to a problem in a context."
What is polymorphism in C#?
Polymorphism, in C#, is the ability of objects of different types to provide a unique interface for different implementations of methods. It is usually used in the context of late binding, where the behavior of an object to respond to a call to its method members is determined based on object type at run time.

The basic principles of OOP involves Abstraction, Encapsulation, Inheritance, and Polymorphism. There are also objects and classes. Together, they stand as the working principle of any object-oriented programming language.
What is delegate in C# with example?
Delegates in C# are similar to the function pointer in C/C++. It provides a way which tells which method is to be called when an event is triggered. For example, if you click on a Button on a form (Windows Form application), the program would call a specific method.
What is polymorphism C#?
Polymorphism, in C#, is the ability of objects of different types to provide a unique interface for different implementations of methods. It is usually used in the context of late binding, where the behavior of an object to respond to a call to its method members is determined based on object type at run time.

Why is single responsibility important in software development?
This reduces the number of bugs, improves your development speed, and makes your life as a software developer a lot easier. However, make sure to not oversimplify your code. Some developers take the single responsibility principle to the extreme by creating classes with just one function.
What is single responsibility?
The single responsibility principle is one of the most commonly used design principles in object-oriented programming. You can apply it to classes, software components, and microservices. To follow this principle, your class isn’t allowed to have more than one responsibility, e.g., the management of entities or the conversion of data types.
Who said a class should have one reason to change?
Robert C. Martin describes it as: A class should have one, and only one, reason to change. Even if you have never heard of Robert C. Martin or his popular books, you have probably heard about and used this principle. It is one of the basic principles most developers apply to build robust and maintainable software.
Who introduced the Solid Principle?
The SOLID principle was introduced by Robert C. Martin, also known as Uncle Bob and it is a coding standard in programming. This principle is an acronym of the five principles which is given below…. Single Responsibility Principle (SRP) Open/Closed Principle. Liskov’s Substitution Principle (LSP)
What is the open/closed principle?
Open/Closed Principle: This principle states that “ software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification ” which means you should be able to extend a class behavior, without modifying it.
What is the DIP principle?
Dependency Inversion Principle (DIP) The SOLID principle helps in reducing tight coupling. Tight coupling means a group of classes are highly dependent on one another which you should avoid in your code. Opposite of tight coupling is loose coupling and your code is considered as a good code when it has loosely-coupled classes.
Why is object oriented design important?
In software development, Object-Oriented Design plays a crucial role when it comes to writing flexible, scalable, maintainable, and reusable code. There are so many benefits of using OOD but every developer should also have the knowledge of the SOLID principle for good object-oriented design in programming. The SOLID principle was introduced by Robert C. Martin, also known as Uncle Bob and it is a coding standard in programming. This principle is an acronym of the five principles which is given below…
What happens if a high module or class is dependent more on low level modules or class?
The above lines simply state that if a high module or class will be dependent more on low-level modules or class then your code would have tight coupling and if you will try to make a change in one class it can break another class which is risky at the production level.
Can developer B modify a class?
Suppose developer A needs to release an update for a library or framework and developer B wants some modification or add some feature on that then developer B is allowed to extend the existing class created by developer A but developer B is not supposed to modify the class directly.
Who wrote the Solid Principles?
Robert Martin, who's credited with writing down the SOLID principles, points out some symptoms of rotting design due to improperly managed dependencies across modules: Rigidity: Implementing even a small change is difficult since it's likely to translate into a cascade of changes.
Why is solid used in programming?
In general, SOLID helps us manage code complexity. It leads to more maintainable and extensible code. Even with big change requests, it's easier to update the code.
What commandments are in Solid?
Three of these would later become part of SOLID: Open-Closed, Liskov Substitution, Dependency Inversion.
Is solid a rule?
SOLID is really a guideline and not a rule. They work in many cases but they're not guaranteed to always work. Just knowing the principles will not turn a bad programmer into a good one. This means that programmers need to understand why these principles make sense.
Is it possible to program in strict conformance to solid?
Programming in strict conformance to SOLID is generally not expected . However, programmers must be aware of SOLID and use them depending on the context.
Do modules have specific responsibility?
A class or a module must have a specific responsibility and nothing more. Put it another way, it should change for only one reason. We can say that the responsibility is encapsulated within the class and there's stronger cohesion within the class.
What is solid in OOP?
In Object Oriented Programming (OOP), SOLID is an acronym, introduced by Michael Feathers, for five design principles used to make software design more understandable, flexible, and maintainable. These principles are a subset of many principles promoted by Robert C. Martin.
Who invented the open/closed principle?
Bertrand Meyer is generally credited for having originated the definition of open/closed principle in his book Object-Oriented Software Construction.
What is the ISP principle?
Interface Segregation Principle (ISP) Definition: No client should be forced to implement methods which it does not use, and the contracts should be broken down to thin ones. The ISP was first used and formulated by Robert C. Martin while consulting for Xerox.
Why are classes, software components and modules that have only one responsibility much easier to explain, implement and understand than ones that?
Classes, software components and modules that have only one responsibility are much easier to explain, implement and understand than ones that give a solution for everything. This also reduces number of bugs and improves development speed and most importantly makes developer’s life lot easier.
What is single responsibility?
Single Responsibility Principle is one of the five SOLID principles which guide developers as they write code or design an application. In simple terms, a module or class should have a very small piece of responsibility in the entire application. Or as it states, a class/module should have not more than one reason to change.
Is above code OCP or SRP?
Above code is implementing both OCP and SRP principle, as each class has single is doing a single task and we are not modifying class and only doing an extension.
When was the term "sOLID" introduced?
Michael Feathers introduced the SOLID acronym in the year 2000. SOLID is a design principle that plays a very important role during Object-Oriented design. Software development becomes easy, reusable, flexible, and maintainable using these design principles.
What is the single responsible principle?
Single Responsible Principle (SRP) Robert C Martin's original definition is, "A class should have only one reason to change". As the SRP name says, each and every module/class should have single responsibility in software, and that responsibility is encapsulated by the class.
Is a member derived or base class?
As base class (Members) is open for extension, derived classes inherited it and extend their functionality as per requirement. In future if we want to add another type, we have to add another derived class.
Who said that clients should not be forced to depend upon interfaces that they do not use?
Robert C Martin' s definition of ISP, “Clients should not be forced to depend upon interfaces that they do not use.”
Can a base class point to a child class?
Base class object can point to any child class objects without any issues as per inheritance hierarchy . The above code throws an error as the Enquiry class doesn’t have an Add method. Let’s implement the Liskov principle. In this case Liskov principle says parent class object can easily replace child objects.
What are SOLID principles?
SOLID is a mnemonic device for 5 design principles of object-oriented programs (OOP) that result in readable, adaptable, and scalable code. SOLID can be applied to any OOP program.
Who developed the solid principles?
SOLID principles were developed by computer science instructor and author Robert C. Martin (sometimes called “Uncle Bob”) in 2000 and quickly became a staple of modern object-oriented design (OOD). The SOLID acronym became commonplace when these principles gained widespread popularity in the programming world.
What is solid in programming?

What should a class contain?
The class should contain only variables and methods relevant to its functionality. Classes can work together to complete larger complex tasks, but each class must complete a function from start to finish before it passes the output to another class.
What is the single responsibility principle?
The single-responsibility principle (SRP) states that each class, module, or function in your program should only do one job. In other words, each should have full responsibility for a single functionality of the program. The class should contain only variables and methods relevant to its functionality.
What is S.O.L.I.D. in C#?
S.O.L.I.D. Principles of Object-Oriented Programming in C#
Does the program modify the original shape?
Further, nothing in the program modifies the original shape, and it will not need to be modified in the future. As a result, the program now achieves the OCP principle.
What are solid principles?
SOLID principles are the design principles that enable us to manage most of the software design problems. It is an acronym for five design principles intended to make software designs more understandable, flexible and maintainable.
Why do we need a design?
Why do we need a design? It is because the only consistent thing about a software is that it is always changing. Many times, clients do not know their requirements. Technology also change, and it changes a lot. It is always going to change. So designers and developers have to accommodate future changes while they are creating the present day software.
What does "dry" mean in programming?
DRY - Do not repeat yourself. It is one of the most important things. It is based on the knowledge that software is constantly changing. For example, imagine that a piece of code is duplicated across five different classes, five different functions. And now, that code needs to be changed. Where will it be modified? It will then be modified at five different places where the code was duplicated. However, if that similar piece of code was extracted into a single and reusable component, it will only be modified at a single place only.
Why is decoupling important?
Decoupling of the code from other modules or applications. It helps reduce complexity of code.
What is the Liskov principle?
The principle suggests that objects of a base class can be substituted with objects of its derived classes without breaking the application. This means that the objects of derived classes behave in a way similar to the base class.
Benefits of The Single Responsibility Principle
A Simple Question to Validate Your Design
- Unfortunately, following the single responsibility principle sounds a lot easier than it often is. If you build your software over a longer period and if you need to adapt it to changing requirements, it might seem like the easiest and fastest approach is adding a method or functionality to your existing code instead of writing a new class or component. But that often results in classes wit…
Real-World Examples of The Single Responsibility Principle
- You can find lots of examples of all SOLID design principles in open source software and most well-designed applications. Such as your Javapersistence layer and the popular frameworks and specifications, which you most likely used to implement it. One of them is the Java Persistence API (JPA) specification. It has one, and only one, responsibility:...
