There are some difficulties that a programmer must overcome in writing an operating system . Following are the difficulties
- There must be a prioritization i.e there must be time critical and priority wise list, because some process are more critical than other.
- There must be a mechanism in place for multitasking, meaning that the computer must be able to switch between multiple active processes.
- There must be interrupt handling scheme, so it can handle the interrupts while executing some process.
- It must maintain the time constrains, i.e scheduling schemes don't allow response time to exceed the time constraint.
- It must be platform independent, means it would work on any hardware.
- It must be secure and user friendly.
- It must be flexible.
- It must be efficient for doing process and utilize all recources.

∙ 12y agoI find that the hardest part of programming is thinking of what to program.
However, for many people, the hardest part is getting their brain in the right frame of view and think the process through. For example, when writing a sorting algorithm, you would think that is pretty easy. But to tell a computer how to do it requires creative thinking.
Everyone has different opinions on programming difficulties, though, so don't take this answer as absolute.

∙ 12y agoI think the main difficulty in real-time programming is meeting the "real-time" requirements, i.e., you are required to accomplish tasks within the real-time constraints which I believe vary. I learnt this in an engineering internship at military and their requirements were quite stringent and mission critical.

∙ 13y agoThis exact same question has been asked and answered several times before. Before asking a question you could get your answer quicker by searching for previous instances of the question and the answer supplied.
Well, on the first place, you have to be a very, very,VERY experienced programmer, with many years of practice.

Why do you think some managers have difficulty in delegating How do you feel they can overcome this difficulty?
Managers usually have difficulty in delegating because of the management style that they adopt. They can overcome this by adopting a democratic style of management.

What are the difficulty that the programmer must overcome writing an operating system for real time environment?
A real time operating system needs to be "event driven" and have the ability to perform certain tasks in a very timely manner. Most true real-time operating systems use interrupts to handle events as they occur, such as a time-critical input message from a serial port or a digital I/O event from some peripheral hardware. Next, there should be some kind of prioritization, meaning that one process may be time critical, such as controlling the rods at a nuclear reactor, but other processes might be a little less critical, such as dimming the hallway lights at the reactor facility after hours. Third, there must be a mechanism in place for "multitasking", meaning that the computer must be able to switch between multiple active processes. Some operating systems create a process "stack" for each process, and if a high priority process is to be activated to handle an event, the operating system simply switches control to the higher priority process by loading the current data from the process stack. A true real time operating system can do that in just a couple clock ticks.
