一、数组分离

using namespace std;
int main()
{
    int a[10],b[10],c[10],i,j=0,k=0;

           {
			   b[j++]=a[i];
          }
		  else
		  {

          }
      	}
      	 cout<<"该数组中偶数有:"<<endl;

             cout<<b[i]<<" "<<endl;
         }
      	  cout<<"该数组中奇数有:"<<endl;
      	  for(i=0;i<k;i++)
         {
             cout<<c[i]<<" "<<endl;
         }
  return 0;
}

#include<iostream>
using namespace std;

    cout<<"请输入十个数字："<<endl;
    for(i=0;i<10;i++)
