For all of you C programmers out there, what standard do you use? What do most C programmers use? I'm learning from K&R so I'm doing C89, strict C which I think will discipline me incase I decide to venture to C++ one day.
In the real world, the standard is largely irrelevant. You code to your compilers and platform. If you need to target multiple tools or platforms, then you might aim at the standard hoping it works on each of the tools you're usin', but there's no guarantees.
Like mike said the standard is irrelevant. In my job I use Texas Instruments proprietary IDE "Code Composer Studio" which generates code that runs on their DSP chips... due to the design of those specific processors there are aspects of the compiler that do not comply with any established standards, you just have to learn as you go (because god knows in the real world you don't have time to read all of the documentation for the platform before you start developing for it)
