Question

Write a program that defines a Print Job structure as follows: 1) An integer job Id 2) A string user name (maximum 25 characters) 3) An integer tray (tray will hold the tray number 1 for 8 1/2 by 11 paper, number 2 for 8 1/2 by 11 paper, and number 3 for 8 1/2 by 14 paper) 4) An integer for paper size (this will hold a percentage: 100% is normal, 150% is 1.5 times the size) 5) A string for whether the pages are to be sorted (all the page 1's together, all the page 2's together) or stacked (1, 2, 1, 2, 1, 2, etc.) 6) A character for whether the documents should be stapled (Y or N) 7) An integer coded for side (221 means to be printed double sided, taking 2 pages and turning it into 1 page, front and back; 121 means to be printed double sided, from a double sided document; 111 means 1 side only to 1 side only or a normal copy) 8) An integer number of copies 9) An integer status (1 means not printed, 0 means printed) Your program will load information from the file jobs.txt. Your program will read in an unknown number of jobs into an array (max of 10). The reading of the files may be done in main(), or you may create a function for this. Your program will utilize four functions: displayMenu(): Will print the following menu and ask for the user's option. This function will return the choice to main. You must validate the user's entry with a loop. ZooooRocks Copy Menu Press 1 to print the next job Press 2 to see the jobs in the print queue Press 3 to see the job have finished printing Press 0 to quit Enter choice: printJob(): Will print the job from the top of the list This function will turn the status from 1 (not printed) to 0 (printed) displayJob(): Will display all the jobs in the list still to be printed. finishedJobs(): Will display all the jobs that have been printed.
