What are C++ preprocessor directives?
C++ preprocessor directives are commands that are processed before the actual compilation of the code. They begin with a '#' symbol.
Can you give me some examples of preprocessor directives?
Sure! Common examples include #include, #define, and #ifdef. Each serves a different purpose in code management.
What does the #include directive do?
The #include directive is used to include the contents of a file, such as a library, into your program, allowing you to use its functions.
How do #define directives work?
The #define directive defines a macro, which is a fragment of code that can be reused throughout your program, often for constants.
