C++

History:

C++ was developed by Bjarne Stroustrup beginning in 1979 at Bell Labs as an extension of the C programming language. It was designed to add object-oriented programming features while maintaining the efficiency and flexibility of C. Initially called “C with Classes,” it was later renamed C++ to signify the incremental improvement over C.

C++ introduced concepts such as classes, inheritance, polymorphism, and templates, which allowed developers to write more modular and reusable code. Over the years, multiple standardized versions of C++ have been released (C++98, C++03, C++11, C++14, C++17, C++20, and upcoming standards), each adding new features and improving language safety and performance.

Today, C++ remains a powerful and widely used language, especially in systems programming, game development, real-time simulations, embedded systems, and high-performance applications. Its ability to combine low-level memory manipulation with high-level abstractions makes it popular among software engineers worldwide.

Exam Structure for C++ Level 1:

Workfrater C# exam is divided in the following sections:

1. Basic Interview Questions:
   WorkFrater will ask your candidate a few basic questions about C++, such as how long they have been learning and using it, examples of projects they’ve worked on, and some technical questions. The candidate will simply answer orally while the website records their responses. This will help your hiring team assess their knowledge of the programming language.
2. Data types and variables:
   Assess knowledge of C++ built-in data types, variable declarations, initialization, and type conversions.
3. Operators and Expressions:
   Evaluate understanding of arithmetic, comparison, logical, bitwise, and assignment operators.
4. Control Flow (if, else, switch, loops):
   Test the ability to write conditionals and loops such as if, for, while, and switch statements.
5. Functions and Parameters:
   Understand how to declare and define functions, use parameters, return values, default arguments, and function overloading.
6. Classes and Objects:
   Test knowledge of object-oriented programming concepts including class definitions, constructors, destructors, inheritance, and polymorphism.
7. Error Handling (Exceptions):
   Test understanding of C++ exception handling using try, catch, and throw.
8. Compiler Questions:
   The candidate is asked to write C++ code that must display a specific output or solve a clearly defined problem. This section evaluates practical coding ability in a real-world context.

Results, videos and documents:

At the end of the exam, the website will generate a PDF file containing your candidate’s results. The document will provide a detailed analysis of their performance and offer valuable insights, including:

• Candidate Score: Total score and individual results for each question
• Global Statistics: Overall exam data such as the average score, number of candidates who passed or failed, average time taken, etc.
• Time Tracking: Time spent by your candidate on each question
• Performance Breakdown: Highlights of the candidate’s strengths and areas that need improvement

A video of the entire exam will also be available. One part of the video will display the candidate’s webcam, while the other will show their screen. This allows you to verify that the candidate did not cheat during the exam.

If you include this exam as a requirement in a job offer, the job offer page will provide additional insights once all candidates have completed the exam. The page will display:

• Ranking: A leaderboard showing candidates ranked from highest to lowest score
• Average Score: The average score of all candidates who have passed the exam
• Summary: A textual overview of candidate results, giving you a clear snapshot of their overall performance
