How the expression is evaluating?

Question

According to precedence rule of C, increment/decrement operators are evaluated right to left. Following this rule I predicted the output of this snippet as:

5 5 4

But the actual output is:

5 5 5

I'm not getting how this expression is being evaluated. Please help me to do so.

Case is not the same while using 16-bit compiler like TurboC. The output in this case is:

5 4 4

Answer 1

Does it mean that prediction of output of some code like that is only conmpiler specific?
