a+ = ++a + --a + a - (10/2) + a++

= 20+ 21 + 19 +20 -5 + a++

= 80 -5 + a++

=75 + 20(++)

=95 .

now, the value of last "a" becomes 21.

Here the expression is-

a++ + --b when a = 20

Then second step it'll be 10 +-b (here for the post increment a will give previous value then a will increment a's value now the expression is 10 + --b, a=11)

So the final expression would be

10+19 = 29

So, 29 is the answer
