Solution 1

Try it this way

VB

dim x as integer = (((8f xor 33) xor cc) xor 6a)

If the number of values is variable, you could write a method:

VB

public Function XOrStack(values as integer()) as integer
    Dim result as integer = 0
    if (values.Length > 0) then
        foreach (value as integer in values)
            result = result Xor value
        Next
    end if
    return result
End Function

I'm a C# guy, so the code above may need tweaking.

Are you sure the brackets are needed?

They probably aren't, but I'm a scope-aholic. :)

The result of multiple XOR operations don't really change if you reorder the XOR-ing via brackets. That's why I am puzzled as to why brackets are needed here.
