Programming questions and answers

Programming is usually divided into two types, Object Oriented Programming (OOP) and Functional Programming. In OOP, objects are created to represent real life things and they interact with each other through methods and procedures. On the contrary, functional programming uses functions instead of objects to perform tasks. These functions are pure and cannot change their input values. Let us answer some of the programming questions.

Explain why a person would choose to use OOP over FP?

An object-oriented program can be thought of as an entity that has its own data and behavior. It acts like a thing in the world and interacts with other objects by sending them messages. The main advantage of this type of programming is that it helps us organize our code in such a way that it becomes easier to understand and maintain. Also, we can create reusable components which we can call from different parts of the programs. However, there are certain disadvantages too. For example, if your program’s logic or database changes then you will have to go back and fix all those places where the function was called. This makes debugging a lot harder than in a purely procedural language.

What are some benefits of using FP vs OOP?

Functional languages are more suited for writing mathematical programs since the lack of side effects means the output will always depend on the inputs. Therefore, you do not need to worry about accidentally modifying state elsewhere in the program. You also don’t need to think about how state should be shared between different parts of the program. There is no explicit “this” concept either, so when working with collections you only care about their contents rather than worrying about what kind of container holds them. Finally, functions can easily be composed into new ones, which leads to extremely powerful abstractions.

Define recursion.

Recursion refers to a function returning itself. A typical example of this is factorial (n). We say that recursive functions run until a base case is reached. If n happens to be zero, then factorial returns 1*2*3… *n! Otherwise, it calls itself again: factorial (factorial (n – 1)). As long as the function keeps calling itself, it keeps going up the chain, eventually reaching the base case. When the recursion stops, we return the last value it calculated.

Describe what static typing is.

Static typing is the idea that every variable in a computer program must belong to exactly one type. While this may seem limiting, it has several advantages. First, it forces programmers to make sure that variables are declared correctly before they start manipulating them. Second, it prevents many common bugs. Third, it ensures that your code won’t compile unless you follow the rules. Static typing can be used in two ways: structural typing and nominal typing. Structural typing checks that all the variables in a program have the same structure. For example, both Int32s and Double are structurally typed because they have the same set of properties. Nominal typing involves declaring each variable explicitly so that it belongs to a specific type. For example, x 5; y 7; z 9; could be written as int x, double y, float z.

Explain why dynamic typing is beneficial in real life situations.

Dynamic typing allows you to use any variable without first knowing what type it is. So, in real-life situations, we use dynamic typing because we want to keep things flexible.

Why does C++ support inheritance?

The key point of inheritance is that it lets you share types across many classes. In C++, you define a class by specifying the types of all the members of the class (including constructors), and giving the name of the class along with its parent class. If the derived class inherits from another class, the compiler automatically generates virtual methods for any member variables defined in the superclass. Inheritance lets you reuse code by storing it in a single place with just minor modifications required to adapt it to the new situation. However, there are some downsides of inheritance. Inherited data cannot be modified outside its own scope.

Even if an object isn’t meant to change, it’s still possible that other parts of the system might try to modify its values. Also, multiple inheritance can lead to ambiguities when deciding whether to call certain method or constructor implementation. These problems arise when trying to write generic algorithms.

Conclusion

Inheritance makes sense in general, but not always. Programming questions are so interesting. It really depends on what you’re trying to do and how much time you have to work with. Hope your programming questions were answered in this article.

Why do we need it?

There are two reasons why you should know how to code: firstly, if you want to be a programmer; and secondly because programming helps solve problems in different areas such as social media marketing, web design, business management, etc.

How can I learn how to code?

The best way to gain knowledge about coding is through practical experience. But if you don’t have any experience with programming, there’s always learning resources available online. You could start by visiting Lynda .They offer lots of free courses on a wide range of subjects such as Java, Python, HTML5, Android Studio, etc. Finally, there are many books which will help you build your skills. We recommend Code Academy’s book for beginners called Learn to Program in JavaScript.

Where can I use my new skills?

Learning to code doesn’t just mean learning how to write programs but also means being able to apply what you’ve learned. If you’re proficient at writing HTML, CSS, jQuery and JavaScript, then you’re ready to make money with them! This is exactly why we created our Online Graphic Design Academy (OGD). Here, you’ll get live projects that require you to apply everything you’ve learned so far. For example, you’ll find tutorials for graphic design, logo design, UI/UX design, mobile app design and much more.

What if I’m not good at maths?

Don’t worry! There’s no need to be a math whiz in order to become a great coder. Just remember that math plays a key role in all aspects of the programming world. So if you think you’re bad at Math, you’re probably going to struggle when learning to code. Fortunately, this isn’t true. In fact, you don’t have to be super talented either. The most important thing is to keep trying and doing practice tests.

Are there jobs out there?

Of course! Programming is one of the fastest growing careers nowadays. And according to Glassdoor, it’s expected to grow by 18% each year until 2024. Not only that, there’s plenty of room for job growth too. By 2020, there will be 1.7 million open developer positions worldwide.

What does a typical day look like?

Your days as a freelancer might vary depending on the company you work for and whether you’re starting a project or working on a specific task. However, here’s a breakdown of what you can expect.9AM – Get up, drink coffee, read news, check email10AM – Work on some freelance tasks11AM – Lunch12PM – Work on some freelance assignments1-3PM – Have lunch, check emails4PM – Finish freelance projects and prepare for the next day

What should I do before applying?

As a freelancer, you should always come prepared for every assignment. That way, you won’t waste time looking for files or images. Your client will appreciate that. Before starting work, you should create a folder where you store all your assets. You should also download a copy of Photoshop, Illustrator, Sketch and other similar apps. Even though these programmes are paid, they are very helpful when building websites and logos.

Can I combine my freelance career with another profession?

You can definitely combine different professions while you’re freelancing. It’s actually quite common. One of the most interesting combinations is between graphic designer and programmer.

Conclusion

Above are coding questions that many people ask. When you combine both fields, you end up having two talents that complement each other perfectly. You can see examples of this type of combination in sites such as Behance and Dribbble. we hope these coding questions answer your own questions.

It might seem like an obvious point but there are many people who think they need to be a coder to learn how to program. This couldn’t be further from the truth. Programming languages and frameworks have been developed with beginners in mind so even if you haven’t had any formal education or training in computer science or programming, you shouldn’t struggle too much, particularly now when online courses and free tutorials abound. There is no shortage of resources available on the internet these days and some of them offer fantastic opportunities to get started. So long as you approach learning with an open-minded attitude and ask questions along the way, you’ll soon pick up new tricks and techniques.

Start simple

If you’re just starting out, it makes sense to start by building small projects. Building a website or creating a basic app can help you build confidence and familiarity with the tools that will come later on. You can also use websites such as Codecademy and Code School to teach yourself JavaScript or Python. When choosing what project to work on, think about which language would create the best value for money. If you decide to go down the route of learning C++ then you may want to consider using Visual Studio Code instead of Sublime Text Editor.

Learn the basics first

Once you have a feel for how web development works, you can move onto more complex projects. Learning HTML5 and CSS3 will allow you to achieve results more quickly, without worrying about compatibility issues. For example, you could develop a site using HTML5 Boilerplate, a popular front end framework used across sites all over the world. Alternatively, if you want to play around with something more powerful, you could learn React JS, AngularJS or Vuejs. By adding in some server side scripting (such as PHP), you can begin producing dynamic pages that interact with data held in databases.

Build a portfolio

There’s nothing worse than making a mistake during a job interview and then finding out that you’ve lost your chance to secure a position. Having a portfolio of completed projects gives potential employers a clear idea of how well you can work independently and how you manage deadlines. A word of caution though – do not make your entire portfolio public. Instead, create a separate folder for each project where only you can see its contents. You can share links to the files in an email to interested parties.

Understand the fundamentals

After completing several projects and gaining experience, you’ll need to understand the core concepts behind web development. It’s important to grasp how browsers interpret HTML and CSS, how JavaScript interacts with other components, and how responsive design affects the overall user experience. After reading a few articles covering these topics, you’ll gain enough knowledge to be able to tackle more advanced material on your own.

Use online communities

The web has brought together thousands of developers from every corner of the globe. As a result, you should never be short of advice when looking to solve coding problems. Online forums provide one of the most effective ways of meeting fellow coders and asking questions.

Get hands-on!

Learning by doing is often far better than simply watching someone else code. Take the time to set up your own personal workspace and try to replicate the steps being demonstrated. This will ensure that you’re working through similar situations and learning at the same pace as others. You can access lots of practical examples for free from online repositories including GitHub.

Conclusion

Web development is a creative career field that allows you to explore new ideas and express yourself. With so many different platforms available to choose from, there are bound to be opportunities for you to get involved. Try to keep yourself motivated by taking part in competitions or joining discussions online. The more you know, the easier it will become to find your next role.
