Can you explain what C++ directives are?
C++ directives are preprocessor commands that provide instructions to the compiler before the actual compilation starts.
What are some common examples of C++ directives?
Common examples include #include, #define, and #ifdef. They help in including files, defining macros, and conditional compilation.
How does the #include directive work?
The #include directive tells the compiler to include the contents of a specified file, allowing code reuse and modular programming.
Can you give an example of using #define?
Sure! You can use #define to create a constant, like: #define PI 3.14, which allows you to use PI in your code.
