标题: 大家看看这个怎么实现
#include<iostream>
#include<string>
  using namespace std;
enum Cpu_rank{p1=1,p2,p3,p4,p5};
  class cpu
  {
  public:
   cpu()
   {
      rank=p1;
      frequency=0.0;
      voltage=0.0;
      cpuid=0;
      cout<<"默认构造函数被调用"<<endl;
      cout<<"cpu"<<getcpuid()<<"被构造"<<endl;
   }
   cpu(enum Cpu_rank rk,double fq,double vl,int cid)
   {
      rank=rk;
      frequency=fq;
      voltage=vl;
      cpuid=cid;
      cout<<"构造函数被调用"<<endl;
      cout<<"cpu"<<getcpuid()<<"被构造"<<endl;
   }
   void stop();
   void run();
   void control();
   enum Cpu_rank getrank()
   {
      return rank;
   }
   double getfrequency()
   {
      return frequency;
   }
   double getvoltage()
   {
      return voltage;
   }
   int getcpuid()
   {
      return cpuid;
   }
  private:
   double frequency;
   enum Cpu_rank rank;
   double voltage;
   int cpuid;
  };
  void cpu::stop()
  {

   cout<<"cpu"<<getcpuid()<<" is stoped!"<<endl<<"enter 'run' to start it;enter 'out' to run another!"<<endl;

  }
  void cpu::run()
  {

   cout<<"cpu"<<getcpuid()<<" is running!"<<endl<<"enter 'stop' to stop it;enter 'out' to run another!"<<endl ;

  }
  void cpu::control()
  {
   char ans[5];
   run();
   while(1)
   {
   cin>>ans;
   if(strcmp(ans,"stop")==0)
      stop();
   else if(strcmp(ans,"run")==0)
      run();
   else if(strcmp(ans,"out")==0)
      break;
   else cout<<"Illegal entering!"<<endl;
   }
  }

  int main()
  {
   cpu cpu1;
   cpu cpu2(p2,1.8,1.2,2);
   for(int i=1;i<3;i++)
   {
      cout<<"Information about cpu"<<i<<endl;
      cout<<"Rank="<<cpu1.getrank()<<"  Frequency="<<cpu1.getfrequency()<<"  Voltage="<<cpu1.getvoltage()<<endl;
   }
   cpu1.control();
   cpu2.control();
   return 0;
}
在main中本想用循环控制变量i来控制输出不同对象的信息（在变量i的控制下输出cpu1和cpu2的信息），可是不知道该怎么实现，麻烦哪位高手指点一下。这里先谢过。
