What exactly do you think your C++ class is lacking when you sign up for an online C++ tutorial class? A couple of things I would say in that situation are support from the instructor and a quick start class to get your feet wet. When I was first looking into this whole C++ thing (not C++ itself, although that’s a different story), I thought that my instructors were good at their job and gave me plenty of guidance. So what happened? My instructors were very busy and/or forgot to show up on time.
That’s when I realised that C++ wasn’t as simple as I first thought. While a high-speed modern C++ compiler can be used for writing many applications, it’s not much good when it comes to interacting with C++ code or using the standard library. For example, most modern C++ implementations of it are quite sluggish and require forklift programming to support parallel execution. Even for basic common applications, such as getting a file size for a JPEG image, this would be a large out-dated use of my time. The best solution for me was moving onto a C++ based language.
The nice part about C++ right from the start is that it has an excellent standard library. One of the major issues I had when trying to run my C++ applications in a virtual machine was that my CPU was always running way over its head in terms of CPU usage even though there were no commands directly involved in the application. In other words, my CPU was always switching back and forth between multiple virtual environments and processes, all of which resulted in high CPU usage. With C++ as my primary programming language, I was able to eliminate this problem (and hopefully others will too) by having a built-in task manager that switches my applications into different tasks each time I run them.
This is pretty much what the Task Manager does on the C++ learning site. It divides your computer into multiple environments (virtual machines) and executes your program(s) in those environments. Each virtual environment is assigned a priority level, meaning some things get CPU time faster, while others (like launching a number of processes at once) will take longer. You can also “break” tasks into smaller subtasks. Each task can be executed in its own virtual environment and only things that are used rarely will get more CPU usage than they’re used to.

One aspect that the C++ service control manager takes care of for me is excessive CPU activity. The transaction response code within the software handles the main loop. Every time an event occurs, the TSC is called and the service manager monitors the response. It checks for any unusual behaviour and executes your code in the best way it can to ensure you don’t have any performance issues. For instance, if there are transactions taking place and nothing is being done in those transactions, the transaction response will be delayed and the processor will run a little slower as a result. This way the software avoids a lot of hangs and crashes and maintains a high CPU utilization rate.
The service control manager also manages all the I/O resources on my PC, so even if a single application is bogged down, the overall performance will not be effected. It’s very unlikely that you’ll come across a situation where an application that’s just running a few seconds late to respond will slow down a server. This one time (s) when an application is bogged down is the main cause of a slow server. This is what the C++ learning site was trying to avoid.
The final big difference that the C++ learning site made to my C++ programming experience is that the offline version allows me to profile and isolate errors and problems more accurately. With the online service however, the user finds out what program or feature is causing the issue, not a group of different issues that are related to every program or feature. With the offline service however, there is always a certain amount of error knowledge required to be able to pinpoint the exact cause of your sluggishness.
My overall impression of the C++ learning site is that they are very helpful with the problems that most C++ programmers encounter. The site does a great job at explaining performance issues and helping you find a good performance optimization tool. They also offer a great deal of information about memory management and high FPS gaming. I have been running the game on a steady frame rate for many months now and have not had any of the game crashing or experiencing any sluggish aiming problems.
