namespace dlove{    template
    
         class ForNextOperator{          //为了实现operator[][]的重载        friend Object;        Object *object;        Int32 receive1;         //第一次接受的operator[]的参数    private:                //全部设为 private 是为了防止..        ForNextOperator(Object *_base,Int32 _rece1):            object(_base),receive1(_rece1){            ;        }       public:        ForNextOperator(const ForNextOperator &fno):            object(fno.object),receive1(fno.receive1){            ;        }       public:        typename Object::value_type& operator[](Int32 _column){            return *(object->base+(object->column*receive1+_column));       //需要重载operator[][]的类需要有表示基址的base,二维数组列数的column        }    };}
    

以二维数组演示:

namespace dlove{    template
    
         class Array2D{        friend ForNextOperator
     
      ;    public:        enum Arribute{ROW,COLUMN};    public:     //类型定义,由于 Array2D 不准备与 STL 兼容;所以只定义一些会使用的        typedef ElemType value_type;    private:        ElemType *base;        Int32 row;      //行        Int32 column;   //列       public:        Array2D(Int32 _row,Int32 _column):            row(_row),column(_column){            base=new ElemType[row*column]();                //分布空间并默认初始化;        }           Int32 get(Arribute arrib){            switch(arrib){            case ROW:return row;            case COLUMN:return column;            }            return 0;        }           ForNextOperator
      
        operator[](int _row){            return ForNextOperator
       
        (this,_row);        }               };}
       
      
     
    

测试:

#include
    
     #include
     
      #include
      
         using namespace std;using namespace dlove;  #define OUTPUTCONTAINER(container) copy(container.begin(),container.end(),ostream_iterator
       
        (cout,"\t"));cout<

            <<"\t";\        }\        cout<
            
              arr2d(3,4);    OUTPUT_ARRAY2D;    for(Int32 ci(0);ci
