A computer program is needed to store jobs in order of priority. Each job has a job number (for example, 123) and a priority from 1 to 10, with 1 being the highest priority and 10 the lowest.
The program stores the jobs in a global 2D array.
The pseudocode declaration for the array is:
DECLARE Jobs : ARRAY[0:99, 0:1] OF INTEGER
For example:
• Jobs [0, 0] stores the job number of the first job.
• Jobs [0, 1] stores the priority of the first job.
The global variable, NumberOfJobs, stores the number of jobs currently in the array.
