描述

实现一个三维数组模版CArray3D，可以用来生成元素为任意类型变量的三维数组，使得下面程序输出结果是：

0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,

注意，只能写一个类模版，不能写多个。

#include <iostream>using namespace std;// 在此处补充你的代码int main(){    CArray3D<int> a(3,4,5);    int No = 0;    for( int i = 0; i < 3; ++ i )        for( int j = 0; j < 4; ++j )            for( int k = 0; k < 5; ++k )                a[i][j][k] = No ++;    for( int i = 0; i < 3; ++ i )        for( int j = 0; j < 4; ++j )            for( int k = 0; k < 5; ++k )                cout << a[i][j][k] << ",";return 0;}

输入

无

输出

0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,

样例输入

无

样例输出

0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,

提示

提示：类里面可以定义类，类模版里面也可以定义类模版。例如：

class A{    class B {    };};templateclass S{    T x;    class K {        T a;    };};

用指针写了个。没写析构函数。不大明白的。没有用到提示

template<class T>class CArray3D{private:T *** _array;int _r,_c,_l;public:CArray3D(int r, int c, int l){_array = new T **[r];for(int i = 0;i<r; i++)          {              _array[i] = new T*[c];          }          for(int i = 0;i<r; i++)          {              for(int j=0; j<c; j++){_array[i][j] = new T[l];}          }        _r = r; _c = c; _l = l;}int ** operator[] (int index)     {          return _array[index];      } };

模板类里定义模板类

template<class T>class CArray3D{public:template <class T1>class CArray2D{public:template <class T2>class CArray1D{public:CArray1D(){a = NULL;}void set(int l){a = new T[l];}~CArray1D(){if(a) delete []a;}T2 & operator [] (int index){return a[index];}private:T2 *a;};CArray2D(){a1 = NULL;}void set(int c, int l){a1 = new CArray1D<T1>[c];for(int i = 0;i<c;i++){a1[i].set(l);}}~CArray2D(){if(a1) delete []a1;}CArray1D<T1> & operator [] (int index){return a1[index];}private:CArray1D<T1> * a1;};CArray3D(){a2 = NULL;}CArray3D(int r, int c, int l){a2 = new CArray2D<T>[r];for(int i=0;i<r;i++){a2[i].set(c,l);}}~CArray3D(){ if(a2) delete []a2;}CArray2D<T> & operator [] (int index){return a2[index];}private:CArray2D<T> * a2;};
