Can I execute any c made prog without any os platform?

Question

I googled about it and somewhere I read ....

Yes, you can. That is happening in the case of embedded systems

I think NO, it\'s not poss

Answer 1

every piece of hardware has to have a piece of software that operates it, be it embedded firmware (smaller and relatively fixed, like vxworks) or an operating system software that can run complex arbitrary code on top of it (like windows, linux, or mac).

think of it as a stack. at the bottom, you have the hardware. on top of that, a piece of software that can control that hardware. on top of that, you can have all sorts of stuff. in the case of a voip phone, you'll have vxworks controlling the hardware, and a layer on top of that that handles all the phone applications.

so going back to your question, yes, you CAN run any c program on anything, BUT it depends what kind of c program it is. if it's a low level c program that can talk to hardware, then you dont need anything other than your program and the hardware. if it's a higher level c program (like a chat program), then you need a whole bunch of stuff between your program and the hardware.

make sense?
