What does mysql_init() return?

Solution (By Examveda Team)

This question is about the mysql_init() function in MySQL. This function is used to initialize a MySQL connection.
Let's break down the options:
Option A: integer - Integers are whole numbers like 1, 2, 3, etc. While mysql_init() does sometimes return an integer to indicate success or failure, it's not its primary return value.
Option B: float - Floats are decimal numbers like 1.5, 2.7, etc. This isn't relevant to what mysql_init() returns.
Option C: structure - A structure is a way to group related data together in a specific format. While mysql_init() works with structures, it doesn't return a structure itself.
Option D: pointer to a structure - This is the correct answer! The mysql_init() function returns a pointer to a structure. This pointer points to a structure called MYSQL, which contains information about the MySQL connection you're establishing.
So the answer is D: pointer to a structure.
