int a=15;
b = a++ + a++ ; //15+16=31 , now a=17, first it's value uses in print and increments next.
a = (b++) + (b++) ; // 31 + 32 = 63
finally a= 63, b=33
but it may produce undefined behaviour also..
cannot predict outcome same on different compilers ( in c/c++) .

in the first operation you can look like
b=last a + new a (15+16)=31
a=17
a=last b + new b(31+32)=63
b=33
