原理就不写在这里了，毕竟网上的介绍有很多，代码如下所示：

复制代码 代码如下:

#include <iostream>

using namespace std;

#defineN5

#defineM10

int main(int argc, char **argv)

{

int **p;

int i,j;

p = new int* [N];

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

p[i] = new int [M];

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

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

p[i][j] = i + j;

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

{

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

{

cout<<"["<<p[i][j]<<"]"<<" ";

cout<<*(*(p + i) + j)<<" "<<endl;

}

cout<<endl;

}

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

{

delete [] p[i];

p[i] = NULL;

}

delete [] p;

p = NULL;

return 0;

}
