What will be the value of the <b>c</b> variable af

What will be the value of the c variable after the following code is executed?

int a, b = a = 0, c;
if (b != a++)
    c = 1;
else if (b == --a)
    c = 2;

0
1
2
Code will not compile
The value of c will be arbitrary

Explanation

Variables a and b are set to 0 in the first line. Variable a is incremented by 1 after the condition check, which is false, in the second line. Therefore, code's execution will be passed to the fourth line. The value of a will be decremented by 1 before the condition check. Condition will become true, therefore variable c will be assigned a value of 2.
