i need code for this program in C++. thanks !

Printer queue (Small document first) Write a program to implement Queue Scheduling DOCUMENTS for printer in which printing would be done on the basis of minimum number pages in a document. Small document first is a scheduling algorithm in which the document with the "minimum number of pages remaining" is selected for printing next Since the currently printing document is the one with the minimum amount of pages remaining by definition, and since that pages should only reduce as printing progresses, document will always run until they complete or a new document is added that has less pages After printing 1 page function check for new documents with fewer pages than it would get selected for printing EXAMPLE Document D1 D2 D3 D4 Total pages Arrival Time 21 6 Insertion and deletion in queue would be D1 D2 D4 D2 D D1 12 32 Printer queue (Small document first) Write a program to implement Queue Scheduling DOCUMENTS for printer in which printing would be done on the basis of minimum number pages in a document.
