1. Which version of C programming is used in MDK -Arm, is it C99.
2. Is Compiler real-view, as in option we get path of compiler as Keil/Arm/RV31. But on Keil website it says compiler is ARM C/C++ Compiler(armcc) . Or both are same.
Which one is default C99 or C90. how to check it.
You should follow the link I provided and read the manual. It says:
For files having a suffix of .c, .ac, or .tc, --c90 applies by default.
Who needs to follow a link when there are helpful people available to do the donkey work?
