I was thinking of learning C++ to really understand computer
programming. A lot of my friends tell me that C++ is faster and good
quality. My question is can C++ create Windows Applications? For
Windows XP? or is C++ limited to open source applications, command
prompt applications? Is it possible to create a real-time application
for Microsoft Windows using C++? I can't seem to find the answer using
keywords in my search engine. I am a bit confused.

Based on your response to the original poster's statement, can your
elaborate a bit on the following PDF document located at http://global.mitsubishielectric.com...l82/82r&d1.pdf on the
World Wide Web. Given that I am not well learned in the area of real-time
computing, processing, or programming, I am interested in learning more on
this subject in relation to programming in the C++ language.
Thank you and have a g'day.

Real-time applications are broadly divided into two types, "hard" and
"soft".
Hard real-time requires that a function be performed within a specified
time deadline, absolutely all the time. This is not possible in
Windows, by design, because the user can run unknown multiple processes
that compete for the CPU time.
Soft real-time requires that a function be performed, on average and
usually, within a desired deadline. It is possible to do this in
Windows, and even more so with the help of specialized device drivers.
For example, playing an audio file is a real-time operation. It is
possible, but unlikely, that there will be pauses in the sound output if
the user does something like startup MS Flight Simulator.

Thank you for sharing your knowledge in this particular area given that I
was not aware of the differences in 'hard' vs 'soft' real-time concepts.
Hence, I understand the original statement posted much better at this point
in time. So, the best case scenario for Windows would be a pseudo real-time
system so-to-speak, agreed? In other words, it's not a recommended choice if
designing a mission-critical system, correct?
Thanks again and have a g'day. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

This is not a troll. I'm language shopping and I want people's answers. I

noticed, however, that every programmer I talk to who's aware of Python is

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
