What is the C++ preprocessor?
An example of an AI chatbot conversation about the C++ preprocessor and its functionalities.
Can you explain what the C++ preprocessor is?
The C++ preprocessor is a tool that processes your source code before it is compiled. It handles directives like #include and #define.
What are some common preprocessor directives?
Common directives include #define for macros, #include for including files, and #ifdef for conditional compilation.
How does the #define directive work?
The #define directive creates a macro that can replace a token in your code with a specified value or code snippet.
Can you give an example of using #ifdef?
Sure! #ifdef checks if a macro is defined. If it is, the code following it will be included in the compilation.
