The answer is 4. because range of char is -128 to 127 so at 140 it get considered as 127,-128,-127,-126,....,-116.
so 120+(-116)=4

The real answer is that any programmer who would write this kind of code should be given the opportunity to work for the competition.

The sequence expression (q=4,r=-12,q) evaluates to 4 (the last element), with the side-effect of assigning r the value -12. So, avg(1,4,-12) = -7/3 = -2.33...
