c programming code

You are to make a simulation of a printer queue. Print jobs will be submitted to the queue and then the printer will print those jobs. You can implement your queue using an array or a linked list. If you use a very efficient structure (either an array which uses an offset integer to avoid shifting elements, or a head- tail doubly-linked list), you will receive bonus marks. Your program will read in input from standard input. If a line begins with a + symbol, a new print job will be added to the queue. If a line begins with a - symbol, a job will be served from the queue. If a line doesn't begin with either, then your program will exit. Each job queue has a print job ID (an integer) as well as a number of pages (also an integer). Here is some example input: + 1 4 + 2 6 + 3 1 - + 4 5 - - - + 5 3 - done And here is the output your program would generate for that input: Printing job 1 (4 pages) (queue is not empty) Printing job 2 (6 pages) (queue is not empty) Printing job 3 (1 pages) (queue is not empty) Printing job 4 (5 pages) (queue is empty) Printing job 5 (3 pages) (queue is empty) You only produce output when a - symbol is seen and you're printing something. Each time you see a - symbol, you serve a job from the queue, display information about it, and display a message saying whether the queue is currently empty or not.
