Answer 2

Answer:

Currently r=5

v=r++ + 2*r +2*r++

Note :-

r++ it's a postfix increment which means "first calculate then increase your value"

So

v=r++ + 2*r +2*r++

= 5 + 2*r + 2*r++ //now r turns 6

= 5+ 2*6+ 2*r++ //r is still 6..no change in value

= 5+ 2*6 + 2* 6 //Now r turns 7

= 5+ 12 + 12

= 5 +24

= 29

Correct Answer:-

• v=29
• r=7
