https://www.nowcoder.com/practice/9e55995c4e5345878a31682e4048a0ed
int ** p = new int* [n];
for (int i = 0; i < n; ++i)
{
p[i] = new int[n];
for (int j = 0; j < n; ++j)
{
p[i][j] = i + j;
}
}
for (int i = 0; i < n; ++i)
{
for (int j = 0; j < n; ++j)
{
cout << p[i][j] << " ";
}
cout << endl;
}
二维数组就是指向一维数组的指针, 即指向指针数组的指针.
