一维数组
int m = 5;
int *arr = new int [m];
delete [] arr;
二维数组
#include <iostream>
using namespace std;
int main()
{
int m = 5, n = 10, v = 0;
//创建指针数组
int **arr = new int* [m];
//为指针数组的每个元素创建一个一维数组，得到arr[m][n]
for (int i = 0; i < m; i++)
{
arr[i] = new int[n];
}
for (int i = 0; i < m; i++)
{
for (int j = 0; j < n; j++)
{
arr[i][j] = v;
v++;
}
}
for (int i = 0; i < m; i++)
{
for (int j = 0; j < n; j++)
{
cout << arr[i][j] << " ";
}
cout << endl;
}
//使用后先删除一维数组
for (int i = 0; i < m; i++)
{
delete [] arr[i];
}
//再删除指针数组
delete arr;
//也可以直接delete [] arr;
return 0;
}
三维数组
int ***array3D;
int m = 5, n = 10, h = 20;
arr = new int **[m];
for( int i=0; i<m; i++ )
{
arr[i] = new int *[n];
for( int j=0; j<n; j++ )
{
arr[i][j] = new int [h];
}
}
//释放
for( int i=0; i<m; i++ )
{
for( int j=0; j<n; j++ )
{
delete arr[i][j];
}
delete arr[i];
}
delete arr;
