Answer 2

Answer:

Explanation:

The NULL constant is defined in many of the header files in the C programming language; including, stdio.h stddef.h , stdlib.h , etc. In C programming, usually, we add stdio.h in the program to use scanf() and printf() functions. So, you don't need to add any extra header files.
