初始化：-init [ < resource num> < priority num> ]
进程与资源管理器的资源数目和优先级数目可以由用户输入确定，默认为4和3**（新增）**
创建进程：-cr
撤销进程：-de
请求资源：-req <# of units>
释放资源：-rel <# of units>
超时：-to
退出：-exit （新增）
打印就绪队列的所有进程：-list ready
打印资源阻塞队列的所有进程：-list block
打印管理的所有资源：-list res
打印管理是所有进程：-lisy pro （新增）
打印程序控制块：-pr
项目采用CLion开发环境，使用cmake进行项目管理，使用git进行版本控制。
注意，可执行文件在cmake-build-debug目录下！
