Question

If x = 15, y = 6 , z = 30. Then evaluate the following
++y + y++ + z % x++ + ++x​

Answer 1

Given,

x=15,y=6,z=30

To evaluate:

• ++y + y++ + z % x++ + ++xx

Solution:-

++y +y++ +z% x++ + ++x

>>>7 + 7 + 30% 15 +17. //Now y is 8 and x is 17

>>>7+7+0+17

>>>31. <= Correct Answer

Explaination:-

• The explaination is very easy ....you just need to understand the concept of Prefix (++x ) and Postfix (x++) increment.
• Prefix increment means first increase then calculate....i.e. First the value will increase then the control moves futher.
• Postfix increment means first calculate then increase.....i.e. First the control moves futher then the value increases.

Therefore, the correct answer is 31.
