voide main()

cin >> m>>n;//输入m行n列的数组

int **p = new int*[N]; //动态申请一个二维数组

//int *p = new int[N];//动态申请一个一维数组

for (int i = 0; i < m; i++)

{

p[i] = new int[n];//每行的列申请的内存

for(int j = 0;j

}

for (int i = 0; i < m; i++)

  }

}

cout<<endl;

//删除刚才分配的列数组内存

for(int i = 0;i

{

delete []p[i];

  }

//删除数组分配的内存

delete [] p;
