This course assumes you have the prerequisite knowledge from the previous two courses in the specialization. You should make sure you have that knowledge, either by taking those previous courses or from personal experience, before tackling this course. Throughout this course you'll build on your foundational C and Unity knowledge by developing more robust games with better object-oriented designs using file input and output, inheritance and polymorphism, and event handling. This course gives you even more tools to help you build great games with C and Unity! This course is the fourth course in the specialization about learning how to develop video games using the C programming language and the Unity game engine on Windows or Mac.

This course assumes you have the prerequisite knowledge from the previous three courses in the specialization. Throughout this course you'll build on your foundational C and Unity knowledge by developing more robust games with better object-oriented designs using various data structures and design patterns. Data structures and design patterns are both general programming and software architecture topics that span all software, not just games. Although we'll discuss these ideas in the game domain, they also apply if you're writing a web app in ASP.
NET, building a tool using WinForms, or any other software you decide to build. To get started, click the course card that interests you and enroll. You can enroll and complete the course to earn a shareable certificate, or you can audit it to view the course materials for free. Visit your learner dashboard to track your progress.
You can access your lectures, readings and assignments anytime and anywhere via the web or your mobile device. You can complete the specialization 24 weeks if you overlap the last week of a course with the first week of the next course. This should work fine because the last week for those overlapping courses has a very light workload.
None, the specialization doesn't assume you have any programming or Unity knowledge when you start. The specialization is designed for you to take the courses in order because each of the courses builds on the knowledge you should have learned in the previous courses. If you have previous C programming experience and have already written some small games in Unity, you can probably shuffle the order around, though you should definitely save the Capstone for last.
You'll be able to program small by commercial standards Unity games using C. Although most of you will certainly need to take more courses and get more experience before you can build commercial-quality games it takes my UCCS students 4 years to get there , this specialization builds a strong foundation for you to build on.

Beginner Level. This results in explicit, deterministic freeing of resources. If you are creating and disposing of an object within the context of a single code block, it is basically inexcusable to forget to call Dispose , because C provides a using statement that will ensure Dispose gets called no matter how the code block is exited whether it be an exception, a return statement, or simply the closing of the block.
It has a second, completely unrelated purpose, which many C developers are unaware of; namely, to ensure that Dispose gets called on an object when the code block is exited:. By creating a using block in the above example, you know for sure that myFile. C continues its enforcement of type safety into runtime. However, once again, programmers can squander this great feature, leading to C problems. The most obvious error that could occur with the use of Method 2 would be a failure to check the return value. That would likely result in an eventual NullReferenceException, which could possibly surface at a much later time, making it much harder to track down the source of the problem.
In contrast, Method 1 would have immediately thrown an InvalidCastException making the source of the problem much more immediately obvious. Moreover, even if you remember to check the return value in Method 2, what are you going to do if you find it to be null? Is there something else you can try if that cast fails? If not, then throwing an exception is the correct thing to do, so you might as well let it happen as close to the source of the problem as possible.
Here are a couple of examples of other common pairs of methods where one throws an exception and the other does not:.
Introduction to C#
While there are certain select cases where this may be true, it is not at all correct as a generalization. As a specific example, in a case where you have an alternative legitimate e. In such a case, it may indeed be better to write something like this:. Use the correct one for the context you are in, remembering that exceptions can certainly be your friend as a developer. While this problem is definitely not C specific, it is particularly egregious in C programming since it abandons the benefits of the strict type checking offered by the C compiler.
Warnings are generated for a reason. While all C compiler errors signify a defect in your code, many warnings do as well. What differentiates the two is that, in the case of a warning, the compiler has no problem emitting the instructions your code represents. A common simple example for the sake of this C programming tutorial is when you modify your algorithm to eliminate the use of a variable you were using, but you forget to remove the variable declaration.
The program will run perfectly, but the compiler will flag the useless variable declaration. The fact that the program runs perfectly causes programmers to neglect to fix the cause of the warning. But if you ignore this type of warning, sooner or later, something like this may very well find its way into your code:. You now have a serious error in your program although the compiler has only flagged it as a warning, for the reasons already explained , and depending on how complex your program is, you could waste a lot of time tracking this one down.
Had you paid attention to this warning in the first place, you would have avoided this problem with a simple five-second fix. They usually only take a few seconds to fix, and fixing new ones when they happen can save you hours. Of course, there are exceptions to every rule.

Accordingly, there may be times when your code will look a bit fishy to the compiler, even though it is exactly how you intended it to be. In those very rare cases, use pragma warning disable [warning id] around only the code that triggers the warning, and only for the warning ID that it triggers. This will suppress that warning, and that warning only, so that you can still stay alert for new ones. C is a powerful and flexible language with many mechanisms and paradigms that can greatly improve productivity.
Using a C Sharp tutorial like this one to familiarize oneself with the key nuances of C , such as but by no means limited to the problems raised in this article, will help in C optimization while avoiding some of its more common pitfalls of the language. C is one of several programming languages that target the Microsoft CLR, which automatically gives it the benefits of cross-language integration and exception handling, enhanced security, a simplified model for component interaction, and debugging and profiling services.
