does it matter which compiler you are using?

Answer 1

Just undefined garbage values stored within the system. Compilers do not check whether or not your array iterations are out of bound.

Answer 2

All I know is that the only thing a compiler does is run your code it shouldn't matter what one you are using it should output the same thing as anything else
