Requirement: In the system, all the processes are grouped into six priority classes, ranged from 1 to 6, according to their membership status. A larger priority number indicates a higher priority. To maximize the system service performance, you are required to implement a scheduling algorithm using multi-level queue strategy with three queues: : a high… Read more A process scheduling algorithms in C

This is a simple implementation of cp command in linux, if you are student in University of Adelaide who happens to take SPC course, please do not copy this code directly. Code still can be optimized but I’m not gonna fix it since no mark will be given for coding style. CP命令的C实现~ Compile： gcc -o… Read more Linux cp command in C
