Which is the header that should be included first?

Solution (By Examveda Team)

This question is about the header files used in MySQL. Header files are like instruction manuals for the compiler, telling it how to use different parts of the MySQL code.

The header file you include first is crucial because it sets up the foundation for other header files to work correctly.

Among the options given, mysql.h is the header file that needs to be included first. It contains the essential definitions and functions for working with MySQL.

Here's why the other options are not the first ones to include:

* my_global.h: This header file defines global variables and functions used throughout the MySQL code. It relies on the definitions in mysql.h to function properly.

* my_sys.h: This file contains system-specific definitions and functions, which are used by other header files and depend on mysql.h.

* my_local.h: This header file provides definitions specific to a particular installation of MySQL, but it also requires mysql.h to work correctly.

Therefore, the answer is Option C: mysql.h.
