3. Conditional compilation.
4. Miscellaneous directives.
5. We’ll also be covering about predefined macros.
Previously we had covered a little bit about File inclusion, you can take a look at it here include directive in C Program
If you’re a computer science student enrolled in University, your syllabus may not include in-depth learning of preprocessors. But when it comes to competitive exams and real-time application programming you’ll have to use preprocessors a lot. So better learn it now.
In upcoming videos we’ll cover preprocessor concepts in detail with simple example programs to explain the concepts/topics.
So stay tuned, stay subscribed to our YouTube channel and blog.
