Technical screening of C and C++ developer skills using an online coding. Technical screening of C or C++ developer skills using an online coding.
The thing you need to be absolutely clear about with C and C++ developers is that it is essential that they have immaculate coding skills. C does allow for any margin of error and C++ does allow for much more. Certainly, a resume screen and phone screen can help you weed out some of your candidates. That said, the last thing you want to do is invite a candidate to a technical interview only to find that they never had the coding skills you need all along.

It is true that you can use almost any language at the back-end, for instance, Google uses C++, Java and Python (along with Go). For low-level data processing, C++ fits the best, for background jobs like updating user's friend recommendations, Java is a good option. C++ allows procedural programming for intensive functions of CPU and provide control over hardware, which it is widely used in developing different games or in gaming engines. C++ mainly used in developing the suites of a game tool.
Future of C and C++, Not only it is a fundamental language but its permissive nature allows the user to manage program memory as it offers the feature of dynamic memory allocation which makes it much faster than any other language. Today, every computer literate person is aware of the term “C/C++ Programming”. Scope of Variables in C++ In general, the scope defined as the extent up to which something can worked with. In programming also the scope of a variable defined as the extent of the program code within which the variable can we accessed, declared, or worked with it.
The Demand for C/C++ in the Market But, it is also important to note that most of the developers know how to code in C and C++. It is the minimum requirement for any programmer to know C/C++ programming to hire. Hence, it is safe to say that C/C++ is the prerequisite of all other languages. In conclusion, C++ in 2020 will continue to remain in high demand owing to its performance, reliability, and the wide variety of contexts in which it can used.
We are happy and proud to say that we have strong relationship with over 700+ small, mid-sized and MNCs. Many of these companies have openings in C & C++. Moreover, we have a very active placement cell that provides 100% placement assistance to our students. The cell also contributes by training students in mock interviews and discussions even after the course completion.
Yes, it is a bright field; there are bright prospects and various avenues in C and C++ programming for candidates with extensive knowledge. If you are not aware of the career in C/C++ Programming, then you have come to the right place. It is also important to note that most of the developers know how to code in C and C++. It is the minimum requirement for any programmer to know C/C++ programming to hire. In India, the pay scale of a C and C++ programmer varies from two lakhs per annum to 30 lakhs per annum. For a novice, who simply did a 2-3 months certification course of C programming is likely to hired by a small-scale organization.
As we know both C and C++ are programming languages and used for application development. The main difference between both these languages is C is a procedural programming language and does not support classes and objects, while C++ is a combination of both procedural and object-oriented programming languages. C and C++ share a similar syntax, this is the aspect of both languages that are most similar. ... This is why it said that C++ is a “superset” of C. Yet remember, this similarity is in syntax only. C is an imperative programming language, whereas C++ is an object-oriented programming language.
Obsoletely, it is based upon a Student, It take an average person to learn all the fundamentals of the C & C++ language. You will get the Syntax of the language quickly (2–3 months with no experience) assuming you have no experience with programming: You are learning 2–4 hours per day 5 days per week.
Our courseware is designed to give a hands-on approach to the students in C & C++. The course is made up of theoretical classes that teach the basics of each module followed by high-intensity practical sessions reflecting the current challenges and needs of the industry that will demand the students’ time and commitment.
Yes, it is a good language to learn because it doesn't hide anything from you and because so many other languages use a similar syntax. In addition, it has some object-oriented design that can help you get ready to take on other languages. C++ is going to be the most effective on big projects when there is many data to manage. ... Moreover, when you will master C++, it will be super easy for you to jump into Java, C# and pretty much most of similar languages. Many of them inherit many functions from C++ so it is definitely useful to learn it.
Future of C and C++ Not only it is a fundamental language but also its permissive nature allows the user to manage program memory as it offers the feature of dynamic memory allocation, which makes it much faster than any other language. Today, every computer literate person is aware of the term “C/C++ Programming”. It has a good future and is a sound investment and often C++ engineers are good at other languages as well, I generally picked up mobile development faster than the specialist Java programmers (true story).... People who major in C++ and competitive programming tend to pick up new technologies faster.

C and C++ Developers:
C and C++ developers get the same buzz as developers in other languages. They are biquitous as JavaScript developers. They are as well connected to hot topics like data science as Python developers. They do use a technology as up-and-coming as Kotlin developers do. But unlike the technologies making all the headlines, C and C++ continue to be the workhorses of many essential systems as well as areas like embedded technology and gaming. As a result, there is still a lot of demand for C and C++ developers.

How important are C and C++ certificates for assessing a candidates coding skills?
There are no respected C/C++ certifications. As a result, it is best to ignore any on a resume as they tell you anything about the candidate skill level.
Other things to look out for on a C or C++ developers resume
Look out for whether the candidate:
Specifies the version of the language they have used
Has worked on a typical C++ project
Has participation in large projects, dealing with unique and stringent requirements
Additionally, if the following are mentioned, technical interviews can assess the candidate based on their publicly visible history:
- Speaking at conferences
- Attending conferences
- Writing articles to technical magazines
- Writing a technical blog
- Contributing to OSS.
- Contributing to answer sites
C and C++ interview questions to ask during a phone/video technical interview
It can be rather difficult to rely entirely on a resume. After all, its important to challenge the candidate on what they claim to see if they actually have the skills or are simply reporting they have them. While a phone interview does make up for a proper coding test, it can help you understand what the candidate thinks and how they go about solving problems.
Questions about the candidate experience
- (C/C++) What were the constraints for your previous projects?
The candidate should be able to share their experience with the given industry. For example, in embedded programming, difficult to use dynamic memory and for games, its very important to ensure that all calculations are finished by the time of rendering one frame.
- (C/C++) Which systems did you program for?
In some ways, programming for Embedded/Desktop and Linux/Windows/OSX is vastly different.
- (C/C++) Were you coding adhering to any specific standards?
The candidate may tell you if they have experience with MISRA etc.
Questions about the candidates knowledge and opinions
- (C++) What are the main differences between C++ and C?
This question will allow the candidate to show their understanding of the languages, as well as whether they treat C++ as a small addition to the C language or a separate language with different usage patterns.
- (C++)What is pointer arithmetic?
This question will the candidate the chance to express their understanding of the fundamental way C deals with memory. Beware: for C++, this question implies using unsafe and outdated patterns in your codebase.
- (C++, entry-level) What is the difference between a class and an object?
To determine whether the candidate understands the basics of C++.
- Which C or C++ online programming test should you choose?
When looking for the right C or C++ online programming test you should make sure they match the following criteria.
- They reflect the real work being done.
- They do take too much of the candidates time, one to two hours max.
- They can be sent automatically and can be taken anywhere
- They go beyond checking whether the solution works to also check the quality of the code and how well it works in edge cases.
- They as close to the natural programming environment as possible and let the candidate access the kinds of resources they normally would at work.
- They let the candidate use all the libraries, frameworks, and other tools they normally would use.
- They are at a proper level that matches the candidate abilities.
