Question

Task (C Language)

Your task is to modify the scheduler in Project 8 so the jobs with higher priority are added before the jobs with lower priority. You will make the following change to the program:

Modify the add_job function such that instead of adding to the end of the linked list, a job is added to an ordered linked list. A new job is added to an ordered linked list by priority. Jobs with higher priority are added before the jobs with lower priority. The list remains ordered by priority after the new job is added. If a new job has the same priority as other jobs, the new job will be added as the last one of the same priority.

Example picture attached below

Example (your program must follow this format precisely)
List of operation codes:
'h' for help;
'a' for adding a job to the scheduler;
'p' for removing a job from the scheduler;
'u' for searching jobs per user;
'j' for searching jobs per capacity;
'1' for listing all jobs;
'q' for quit.
