For more than one format specifiers, why compiler evaluate it from the last ?

Question

Like if there is( "%d%d%d%d", i ,i++,i--,++i)...so why the order of evaluation in C is 4-3-2-1, means from the last . Please Explain me.

Answer 1

What matters here is not the format specifier, it is multiple access and modification of the arguments that matters, the output is compiler implementation dependent, we can't expect a firm output because of this.

Tips: Avoid at best, accessing and modifying a value in a sequence point, how the operation is performed is unpredictable.
