2、 需要提供排序操作；实现对设备的插叙需要提供查找操作，设备的查询可根据设备编号、设备种类、设备名称、设备购入日期、正常设备（未报废的）等多种方式查询；另外还要提供键盘式选择菜单以实现功能选择。三. 总体设计根据上面的需求分析，可以将这个系统的设计分为以下模块四. 详细设计1 主函数流程图程序mai n()主函数 *intn , w, t; for(t=0;t6)/*对选择的数字作出判断*/ w=1;getchar();else w=0; while(w=1);switch( n)case 1:t=enter();break;/*输入模块 */case 2:t=enter(); break;/*
