Advanced Conditional Macros

We've considered the basics of Conditional Macros, and how to assemble and use the macros #if, #elseIf, #else, and #endIf. We've also looked at the simplest operators: == (equal to) and != (not equal to).

Now we're going to consider the more advanced features of conditional macros:

• Nest conditional macros
• Combine conditional macros with the && (AND) and || (OR) operators
• Negate a condition
• Use parentheses to group sets of conditional statements
