Symbian and BeOS are dead. Apple's software is written in C (BSD Kernel+userland), Objective C (not C++) and now Swift.
ARM "operating system" is hardly used extensively.
Arduino's are embedded devices and can be programmed in any language but are hardly applicable across the vast range and scale of Linux deployments.
IBM's primary operating systems that aren't Unix based are written in Assembler or even RPG.
- pjmlp 5y agoI advise yourself to get acknowledged with IO Kit, Drivers Kit and Metal graphics subsystem. IBM mainframes are written in mix of PL.8 and PL/S originally, with newer code being C++. ARM apparently doesn't have any issues getting their stuff used in medical devices.
