C Program To Implement Priority Scheduling Algorithm

Learn How To Implement Priority Scheduling Algorithm in C Programming Language. The  Priority Scheduling Algorithm is a Disk Scheduling Algorithm for processes that are needed to be executed. The Priority CPU Scheduling Algorithm is normally represented using Gantt’s Chart on paper.

The Priority Scheduling Program in C Language is normally implemented in Operating Systems to schedule multiple process entering the CPU for execution. This code is for Priority Scheduling Non – Preemptive Algorithm in C Programming.

What is Priority Scheduling Algorithm?

In a Priority based Scheduling Algorithm in Operating Systems, every process is assigned a Priority Number. Based on this Priority Number, the processes are executed. This scheduling algorithm is normally very useful in real-time systems. The process having the highest priority (1) is executed first and then priority 2, 3 and so on.

This is a Non – Preemptive Algorithm for Priority Scheduling which means unless a single process gets completely executed, the CPU will not leave the current process and execute any other process. Once a process is completed, only then another process is taken for execution. In other words, the process under execution can be temporarily suspended. You can also modify this code to make it Preemptive Priority Scheduling Program in C Language.

    How do we process when two processes have the same priority?

    • September 7, 2016 at 12:21 pm

      If two processes have the same priority, then the process that comes first in the queue will be executed first.

    The priority scheduling concept truly relates to real life task scheduling.
