Pre- & Post Increment in C#

Question

I am a little confused about how the C# compiler handles pre- and post increments and decrements.

When I code the following:

int x = 4;
x = x++ + ++x         


        

Answer 1

I think the explanation for the ++ + ++ case is wrong:

command...........value of x

..................undefined

int x=4 ..........4

x++...............5 (first summand is 4)

++x...............6 (second summand is 6)

x=summand1+summand2 ..4+6=10

Analogous the explanation for the -- - -- case is

command...........value of x

..................undefined

int x=4 ..........4

x--...............3 (subtactor is 4)

--x...............2 (subtrahend is 2)

x=subtractor-subtrahend ..4-2=10
