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
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。
#includeusing namespace std; // 在此处补充你的代码 int main() { CArray3D 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 {
};
};
template
class 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 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 ————————————————————————————————————————————————————————————————————————————
模板类里定义模板类
template
class CArray3D
{
public:
template
class CArray2D
{
public:
template
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[c];
for(int i = 0;i & operator [] (int index)
{
return a1[index];
}
private:
CArray1D * a1;
};
CArray3D()
{
a2 = NULL;
}
CArray3D(int r, int c, int l)
{
a2 = new CArray2D[r];
for(int i=0;i & operator [] (int index)
{
return a2[index];
}
private:
CArray2D * a2;
};
