C++ Program (Source Code) for Priority Scheduling CPU Scheduling Algorithm

Priority Scheduling:

In operating systems, tasks that are queued to be processed go through different scheduling algorithms in different operating systems. Priority Scheduling is one of them.
Priority scheduling is like shortest job first except that the next job to process is selected not by the amount of time it will take, but by the priority of the job. So in this priority scheduling each job has a priority value associated with it. The task with shortest priority value gets preferred.

Priority Scheduling CPU Scheduling Algorithm in C++ with Explanation: 

This method is quite same as the SJF but the difference is that instead of choosing the next process to work on by the shortest burst time, CPU chooses the next process by the shortest priority value. Here, all the processes are given a priority value. The process with the shortest (The most shortest is 1) priority will be worked on first and so on. Now consider a CPU and also consider a list in which the processes are listed as follows,

Arrival
