how to compare 2 hex string values
- Thread starter Lorey

No, that compares the string pointers.
If you're sure the hex values both start (or don't start) with 0x and have the same number of hex digits, you can compare them with strcmp.
If you're not sure, convert both to integers to atol(), then use ==.

She didn't say anything about pointers, so I'm assuming she's just storing numbers between 0-255 as unsigned chars. In that case, using == is all you need. If it's a char string, then convert them both to lower-case (or upper-case) and use strcmp().
