Answer : Option D
Explanation :
C Operator Precedence Table
According to precedence table execution of the given operators are as follows:
1. x++(Postfix operator) i.e x will become 5
2. y--(Prefix operator) i.e y will become -11
3. * and / have same priority so they will be executed according to their associativity i.e left to right. So, *(Multiplication) will execute first and then /(division).
4. -(Subtraction)
So the complete expression would be
5 - (-11)*2/4 = 5 - (-22)/4 = 5 - (-5) = 5 + 5 = 10.
