Short question concerning 'if'

Take a look at this code:

int number = 9;
if ( number++ == 10)
cout << ”True” ;
else
cout << ”False";

Nevermind the bad formatting, does this code result in "true" or "false"?
To me, it is obvious that 'number++==10' is true if 'number' initially has the value '9'. The thing is, I just did a test for an internet C++ course that I am attending, which gave us this code. When I chose that the result would be "true", I got a message stating that "false" was the right answer.

Have I missed something, or is it the test that was faulty?
The only thing I can think of is the position of '++', and that 'number++' makes the addition to number after the sentence in which it is written. But I do not know if that is the case.

False, since you are using the post-increment operator ++

Try:

Code:

---

int number = 9;
if (++number == 10)
    cout << "True";
else
    cout << "False";

Thanks for your fast reply.
Can I ask you, if '++number' makes the change to number instantly, when does the post-increment ++ take effect?

Also immediately, but the value of the expression is the old one.

++var: var is incremented, the value of the expression is the new value of var.
var++: var is incremented, the value of the expression is the old value of var.

I see, both take effect immediately but the value of the expressions are different?
That explains it. ;-)
