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

Obviously, you cannot execute any arbitrary C program without some sort of OS or OS-equivalent. Similarly, I can write a C program under Linux that won't run under Microsoft Windows.

However, you can write C programs on almost anything. It's a popular language to write software for embedded systems in, and they very often don't have an OS.

Many embedded systems have just a CPU hooked up to a ROM, with pins coming out of the chip that are directly attached to inputs and outputs. There is no user I/O, no file system, no process scheduling, nothing you'd typically want an OS for. In those cases, a C programmer might write a program that is burned into a ROM, which will handle everything itself.

(Some embedded systems are more complicated, and can use an OS. Linux is frequently used, since it's free for the use, can be made very compact, and can be changed at any level. Not all do, though.)
