| | Hi. Can someone tell me how to output a two-dimensional priority queue please? In particular I am using an array of priority queues. The method I use to output an array of vectors is not working. I will show the one that is working (array of vectors): if(!diskQueues[i].empty()) { for …  |
| | Hi. I want to output all of the processes in the printer queue here, and I'm not able to figure out quite how to do that. The only process that shows up is the last one I entered. For instance, if I put a process into printer queue 1 and … |
| | If I prompt the user for n number of printers, is there a way of creating n number of vectors on the fly as opposed to creating vectors and putting them in your class structure at the start? I have to create as many printer queues as a user specifys. … |
