C++ 实现动态定义三维内的数组

//动态定义一维数组、二维数组、三维数组

#include<iostream>

#include<ctime>

using namespace std ;

int main()

{

int hight , row , col ;

register int i , j , k ;

srand((unsigned)time(NULL)) ;

cout<<"输入一维数组的行"<<endl;

cin>>row ;

//动态定义一维数组

int *p1 ;

p1 = new int [row] ;

//输入一维数组的值

for( i = 0 ; i < row ; i ++ )

p1[i] = rand () % 10 ;

//输出一维数组

for( i = 0 ; i < row ; i ++ )

cout<<p1[i] <<' ' ;

cout<<endl;

//释放一维数组

delete [] p1 ;

cout<<"输入二维数组的行，列 :";

cin>>row >>col ;

//动态定义二维数组

int **p2 ;

p2 = new int*[row] ;

for( i = 0 ; i < row ; i ++ )

p2[i] = new int[col] ;

//输入二维数组的值

for( i = 0 ; i < row ; i ++ )

for( j = 0 ; j < col ; j ++ )

p2[i][j] = rand() % 10 ;

//输出二维数组

cout<<"输出二位数组："<<endl;

for( i = 0 ; i < row ; i ++ )

{

for( j = 0 ;j < col ; j ++ )

cout<<p2[i][j]<<' ' ;

cout<<endl;

}

//释放二维数组

for( i = 0 ; i < row ; i ++ )

delete []p2[i] ;

delete []p2 ;

cout<<"输入三维数组高，行，列 : ";

cin>>hight>>row >> col ;

//动态定义三维数组：

int *** p3 ;

p3 = new int**[hight ] ;

for( i = 0 ; i < hight ; i ++ )

p3[i] = new int*[row] ;

for( i = 0 ; i < hight ; i ++ )

//输入三维数组值：

for(i = 0 ; i < hight ; i ++ )

for(j = 0 ; j < row ; j ++ )

for( k = 0 ; k < col ; k ++)

//输出三维数组：

//释放三维数组
