Conditional Compilation
Learn how to use preprocessor directives to compile code conditionally.

Conditional Compilation
Conditional compilation allows code to be included or excluded based on specific conditions.
In this lesson, you will learn:
- How to use
#ifdefand#ifndeffor conditional compilation. - How to use
#if,#else, and#endifto control compilation flow. - How conditional compilation helps create platform-independent code.

Using #ifdef and #ifndef
The #ifdef directive includes code only if a macro is defined.
Example:
#ifdef DEBUG
printf("Debug mode enabled\n");
#endif
The #ifndef directive works oppositely, including code only if a macro is NOT defined.
