[OS Develop] pcb DL : 0: 设计一个有N个进程并发的进程调度程序，采用时间片轮转算法。 Ø 每一个进程用一个进程控制块PCB表示。PCB包含信息有：进程名name，进程号id，进程状态state，进程所需运行时间need_time,进程运行时间run_time。 Ø 进程所需的运行时间人为指定。进程运行时间以时间片为单位进行计算。（程序中以按任意键表示运行一次CPU时间片） Ø 每个进程的状态有就绪W，运行R，和完成F（撤销进程）。 Ø 就绪的进程获得CPU后只能运行一个时间片，运行完运行时间run_time+1。 Ø 如果运行一个时间片后，进程的run_time等于need_time（即已经达到所需运行时间），则撤销该进程并提示，如果还未达到，则将其放到队尾，进入就绪状态等待下一次时间片分配。每一次调度程序都打印一次运行情况，包括：运行的进程，就绪队列的进程，已经所有进程的PCB（不包括已经撤销的进程）。 -The N processes concurrent process scheduler design a round-robin algorithm.

Each process has a process control block (PCB) representation. Process control blocks can contain the following information: process name, priority number, arrival time, run time, CPU time, process status, and so on. The priority number of the process and the required run time can be specified artificially (or by random numbers). The process's arrival time is the process's input time. The running time of a process is calculated as a time slice. The state of each process can be one of the three states of ready W (Wait), running R (Run), or completion of F (Finish). Once the ready process gets CPU, it can only run one time slice. Represented by taking CPU time plus 1. Each time the scheduler prints a run, a ready queue, and the PCB of each process for inspection.)
