Which preprocessor directives are used to report warnings or errors to the compiler?

#warning and #error
#define and #ifdef
#pragma and #line
#if and #endif

The correct answer is: #warning and #error

The preprocessor directives used to report warnings or errors to the compiler are indeed #warning and #error. The #warning directive generates a warning message during compilation, alerting the developer to potential issues without stopping the compilation process. This is particularly useful for notifying developers about deprecated code or other non-critical issues they should be aware of during the build process. On the other hand, the #error directive forces the compiler to stop the compilation and report an error message. This is used when certain conditions in the code are not met, and continuing the compilation would lead to further issues down the line. This helps ensure that the developer addresses critical problems immediately rather than allowing the compilation to proceed with known errors. In summary, #warning and #error serve distinct purposes in communicating directly with the compiler regarding issues in the code, making them essential for maintaining code quality and managing potential problems during software development.
