hope this will help you

Answer 2

The correct answer is option (c) 23.

• The given expression is ++z + y - ( --y) + ( --z) + x ++, where ++Z means that the value will first increment by 1, and its final value will be used in the expression, and x++ means that the original value of x will be used and after that, it will be incremented by 1.

• Now, putting the values in the expression ++z + y - ( --y) + ( --z) + x ++ = 11+5-4+9+3 = 23. Hence, the value of the expression is equal to 23.
