![]() The next nop lines contain four variables: process name(pname), priority(priority), arrival time(atime) and burst time(btime). The first line is the number of processes(nop). Hence, we will write the program of the Priority Scheduling algorithm in C++, although, it’s very similar to C. We will use C++ to write this algorithm due to the standard template library support. ![]() This process is repeated while all process gets executed. Also, if two processes have the same priority then compare to process number (less process number first). Each process is assigned first arrival time (less arrival time process first) if two processes have the same arrival time, then compare to priorities (highest process first). Priority scheduling is a preemptive algorithm and one of the most common scheduling algorithms in batch systems. In this post, we will discuss the Priority Scheduling algorithm and also write a program for the Priority Scheduling algorithm. ![]() There are several different CPU scheduling algorithms used nowadays within an operating system. ![]() CPU scheduling treats with the issues of deciding which of the processes in the ready queue needs to be allocated to the CPU.
