操作系统全体报告-实验八

请在以上示例实验程序中补充SCAN，C-SCAN，LOOK磁盘移臂调度算法的模拟程序。输入不同的磁盘柱面请求序列，观察和分析其调度效果和性能，并将其与FCFS和SSTF磁盘柱面请求序列，以便能动态的观测各种调度算法的性能拟算法的编程技巧，锻炼研究分析试验数据的能力。CPU:I5-4210/2.6GHz内存:4GB硬盘:Ubuntu14.0.4-Linux操作系统gccversion的同方向磁道，直到回到0，然后反方向扫描0，然后回到起点，从最大磁道开#include<iostream>#include<iomanip>#include<malloc.h> usingnamespacestd;classDiskArm{voidInitSpace(char*MethodName)voidReport(void);//报告算法执行情况voidFcfs(void);voidSstf(void);voidScan(void);//电梯调度算法voidCScan(void);voidLook(void);//LOOK调度算法int*Requestint*Cylinder;intintintintint#include"dask.h"intcout<<"PleaseinputCurrentcylinder:";cin>>CurrentCylinder;//磁头方向,输入0表示向小道号移动,1表示向大道号移动cout<<"PleaseinputCurrentDirection(0/1):";cin>>SeekDirection;cout<<"PleaseinputRequestNumbers:";cin>>RequestNumber;cout<<"PleaseinputReqylinderstring:";Request=newint[sizeof(int)*RequestNumber];Cylinder=newint[sizeof(int)*RequestNumber];for(i=0;i<RequestNumber;i++)cin>>}}voidDiskArm::InitSpace(char*{intcout<<endl<<MethodName<<endl;SeekNumber=0;SeekChang=for(i=0;i<RequestNumber;Cylinder[i]=}//统计报告算法执行情况voidDiskArm::Report(void){cout<<endl;cout<<"SeekNumber:"<<SeekNumber<<endl;cout<<"ChangDirection:"<<SeekChang<<endl<<}void{intCurrent=CurrentCylinder;intDirection=SeekDirection;cout<<for(inti=0;i<RequestNumber; &&!Direction)||((Cylinder[i]<Current)&&Direction)){SeekChang++;//调头数加DirectionDirectioncout<<endl<<Current<<"->"}elsecoutCylinder[iSeekNumber+=abs(Current-Cylinder[i]);Current=Cylinder[i];}}void{intintDistance=999999intDirection=SeekDirection;intCurrent=CurrentCylinder;cout<<for(inti=0;i<RequestNumber;for(intj=0;j<RequestNumber;if(Cylinderj]==-1)continue;//-1表示已经响应if(Distance>abs(Current-Cylinder[Distanceabs(Current-Cylinderj]);Shortest=j;}}if(((Cylinder[Shortest]>=Current)&&!Direction)||((Cylinder[Shortest]<CurrentCylinder)&&Direction)){SeekChang++;//调头数加DirectionDirectioncout<<endl<<Current<<"->"<<}elsecout<<"->"<<Cylinder[Shortest] -Current=Distance=999999;Cylinder[Shortest]=-}}voidintCurrent=intDirection=SeekDirection;cout<<for(inti=0;i<RequestNumber;i++){intindex=-1;intDistance=for(intj=0;j<RequestNumber;j++){if(Cylinder[j]==-1)nder[j])<Distance)}}}}elseif(Direction==1){}}}}voidintCurrent=CurrentCylinder;intDirection=SeekDirection;cout<<for(inti=0;i<RequestNumber;i++){intindex=-1;intDistance=for(intj=0;j<RequestNumber;j++){if(Cylinder[j]==-1)nder[j])<Distance)}}}}elseif(Direction==1){}}}}//LOOK调度算法void{intCurrent=intDirection=SeekDirection;cout<<for(inti=0;i<RequestNumber;i++){intindex=-1;intDistance=for(intj=0;j<RequestNumber;j++){if(Cylinder[j]==-1)nder[j])<Distance)}}}}elseif(Direction
