Some operating systems (such as UNIX or Windows in enhanced mode) use virtual memory. Virtual memory is a technique for making a machine behave as if it had more memory than it really has, by using disk space to simulate RAM (random-access memory). In the 80386 and higher Intel CPU chips, and in most other modern microprocessors (such as the Motorola 68030, Sparc, and Power PC), exists a piece of...

Here the 1st answer is 22 and second is 15 because in case of ++a + ++a + ++a then 1st increment then addition let temp=(++a + ++a)==7+7=14 and then ++a =14+8=22
and for 2nd case 5+5+5=15.

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...

The answer is -2.
Expressions are calculated from left to right and so we have:
a/b=1, (a/b)/c=0 (rounding down).
c*d/b is also calculated the same way to give 3.
So -2+3-3 = -2
