C++ offers advantages over C# for systems programming and developing device drivers that require low-level access, as C++ programs can be compiled to run directly on hardware while C# code runs on a virtual machine. Specifically, C++ supports template metaprogramming, typedefs, const-correctness, and produces highly optimized code. While some device drivers can now run as user-mode applications in Windows, C++ remains more suitable for kernel-level drivers. The example then demonstrates a simple "Hello World" C++ program using cout to display output.

- 1. C++ and C# comparison Mr. A / 3 days ago C++ and C# comparison When talk about C++ and C# has enjoyed huge number of programmers, but since C++ trend is beginning and why not? It is the best among the languages which provide bread and butter for actual system programs. As far as job opportunities are concerned. Here is the whole article http://www.arcos.inf.uc3m.es/~jdaniel/sem-cpp-11/Madrid-bs.pdf By looking at those links, C++ nowadays , is in lime light just like C# when it was launched. You can’t write device drivers that runs in kernel mode in C#. C# produces intermediate language that is interpreted by a virtual machine (.NET). All these stuff runs in user mode and WDM drivers run in kernel mode. You can’t write device drivers in managed code, therefore you can’t write a device driver in C#. You’ll need to write it in either assembly or unmanaged C/C++. We can not develop kernel drivers with C# because C# is converted to native language. However, not all device drivers on Windows require kernel mode to run. The video drivers, audio drivers, now run in user mode in both Windows Vista and Windows 7. Also there’s now a User-Mode Driver Framework available from Microsoft. but still C++ leads.What C++ offers that is not present in C# are 1. Template metaprogramming 2. Typedefs 3. Zero-overhead principle 4. Means to enforce const-correctness 5. Mature compilers that produce extremely optimized code nowadays 6. Much wider platform support Can asp.net application be built with C++ language ? The bad aspects of modern languages like C#, Java etc is huge memory consumption due to heavy platform installation, and if users have to work with them, they have to install these platforms. C++ applications are faster to launch. An important point to be noted is that, C++ is Borland property, therefor it is not the language of choice for Asp.Net application. It is for system or game programer
- 2. Begin C++ Programming Since we have debated on the facts where C++ has edge over other language. Let us start writing something with C++ editor in order to begin C++ programming. In my case, it is visual studio 2012 development IDE due to its enormous features. Our first program is Hello C++ and let us see what we have to do with our C++ development IDE. Remember one thing before learning something new is to have love for this features. Your love, passion and hunger will make you the champ, not those hurting words that common people often use. Just keep them aside.Always think like that their profession is to talk non-sense or to make joke. In simple, these sort of people are dumb.So, you are the best and think like this 200 times a day. Our first program is quite simple, it uses cout for displaying output to the console. Program /*Pre-compiled headers can greatly speed the up the compilation of the .cpp files in your project. By convention, it is stdafx.h that #includes all of the .h files that you want to be precompiled. You can name it anything you want but the project template just picks stdafx.h*/ #include “stdafx.h” //The iostream library is an object-oriented library that provides input and output functionality using streams. #include // namespace std contains many classes using namespace std; int main() { // cout is used to display out put on console cout << "hello C++ lovers.n"; return 0; }
