Solution for QID #68856: Instructed to code a C program by my instructor that should | StudyHelpMe

Instructed to code a C program by my instructor that should display the output further below. I also provide input data to provide the correct output further down in this. So, the following C program has 3 files. (main.c, stock.h, stock.c). Basically, I am told NOT to change the main.c file at all instructed by my teacher and create two other files which are stock.c and stock.h to help provide the correct output for this program.   main.c not to be changed so no changes required. stock.c contains functions (black box processes). There ARE bugs stock.h contains data structures. There ARE bugs.   I need the bugs fixed in stock.c and stock.h. This should allow for the program to run and match the output further down after you have read the files and corrected them.   main.c (INSTRUCTED TO NOT CHANGE THIS FILE, LEAVE IT AS IS)   #define
