What is the primary use of the static keyword inside a function?

To declare function arguments.
To initialize variables to zero.
To retain variable value between function calls.
To optimize the function for speed.

The correct answer is: To retain variable value between function calls.

The purpose of the static keyword inside a function is to retain the value of a variable between multiple function calls. This means that the value of the variable will remain the same even after the function has been executed and returned. Options A and B do not accurately describe the use of the static keyword, as using it does not declare function arguments and it does not necessarily initialize variables to zero. Option D is also incorrect because the static keyword does not specifically optimize the function for speed, but rather it retains the variable value.
