Experiment two--simulating process scheduling in the CPU (first draft)

First, Experimental Purpose

This experiment can deepen the understanding of the concept of process control block and process queue.

Second, experimental content and requirements

1. Definition of the structure of the process PCB

2. Define the structure body

3. Enter the process sequence

4. Sort (by time in place)

5. Output process Run results

Third, Experiment Code and results test

Experiment Summary:

VC is not very easy to use, the change in the body of the loop to save multiple times will cancel the error prompt;

Using the method of the array to write the need to leave a large memory;
