The debate over whether Unreal Engine uses C++ or C has been ongoing for several years now. While both engines support both programming languages, there is still some confusion about which one is the better choice for developers. In this article, we will explore the pros and cons of using C++ versus C in Unreal Engine and help you make an informed decision about which one to use for your next project.
C++ vs. C: What are the main differences?
One of the main differences between C++ and C is their syntax. C++ is a statically-typed language, meaning that variables must be explicitly declared before they can be used. This requires more lines of code, but it also makes the program more efficient because the compiler knows exactly what data types are being used.
C, on the other hand, is a dynamically-typed language. Variables do not need to be explicitly declared before they can be used. Instead, the type of the variable is determined at runtime based on the value assigned to it. This makes C code more concise and easier to read, but it can also make it slower than C++ because the compiler has to constantly check the data types being used.
Performance
Another major difference between C++ and C is performance. C++ is generally considered to be faster than C because it is a lower-level language that allows for more control over the underlying hardware. This makes it a good choice for games and other applications that require high performance.
Ecosystem
The ecosystem surrounding each language is also an important factor to consider when choosing between C++ and C in Unreal Engine. C++ has a larger community of developers and a wider range of resources available, including tutorials, forums, and libraries. This can make it easier to find help and support when working with C++.
C, on the other hand, is more closely tied to Microsoft’s .NET framework. This means that there are fewer resources available for developers who are not familiar with .NET, but there are also many powerful tools and libraries available within the .NET ecosystem that can help speed up development.
Learning curve
Finally, the learning curve for each language is an important consideration. C++ is generally considered to be more difficult to learn than C because it requires a deeper understanding of computer architecture and programming concepts. This can make it harder for developers who are new to programming to get started with C++.
C, on the other hand, is designed to be more accessible to developers who are new to programming. It has a simpler syntax and easier-to-understand concepts, making it a good choice for beginners. However, this also means that more experienced developers may find C to be less powerful and flexible than C++.
Case studies: What real-world examples can we learn from?
One of the best ways to understand the pros and cons of using C++ versus C in Unreal Engine is to look at real-world examples. Here are a few examples of projects that have been developed using both languages:
The Witcher 3: Wild Hunt
The Witcher 3: Wild Hunt was developed using Unreal Engine and C++. This massive open world game required high performance and complex graphics, making C++ the natural choice for developers. The game’s lead developer, Tomasz Gajda, has said that C++ allowed them to achieve the game’s stunning visuals and smooth performance without any significant trade-offs.
