Tip of the day!

Pre/Post increment

In pre-increment operand will be altered in value before it is utilized. In post-increment operand will be altered after it is utilized.

In the above snippet 

x = ++a is equivalent to

a = a +1 then

x = a

y = b++ is equivalent to

y = b

then b = b + 1

So the value of y = 10 and b = 11
