1. ## ***** Post-Fix Operator???****

Whats a post-fix operator

i need it to help me answer this question...
Which of the following operations has a higher PRECEDENCE: a post-fix operator or unary operator?

2. int a = 5;

++a; //prefix increment operator
a++; //postfix increment operator

Check out "Operators" under the following link:

I think the answer is unary operator. If you use the - operator postfix it would be like this:

4 - 3

prefix it would be:

-4 - 3

So, if that expression gets ouput as -7, then unary has higher precedence than postfix. On the other hand, if it gets output as -1, then postfix would have higher precedence.

However, the postfix increment operator ++ is also a unary operator, in which case it would be a tie.

3. At Precedence Level 2:

increment operator, postfix-- x++

decrement operator, postfix-- x--

At Precedence Level 3:

All unary operators-

increment operator, prefix ++x

decrement operator, prefix --x

So this means postfix has higher precedence than prefix.
