很急！哪位高手帮我把这段代码用指针改一下。先谢了！

[liuxiang027]

代码我已经写好了。功能也能够实现。现在就是要用指针写。怎么改啊？请高手帮帮忙！很急！拜托了！

这是这个头文件
怎么改？

[liuxiang027]

那个怎么出现有两个*的啊？

[laiwusheng]

二维数组改为二级指针

[jixingzhong]

那个怎么出现有两个*的啊？
＝＝＝＝＝＝＝＝＝＝＝＝＝
1 个就可以了 ！！

比如：
void OutputScore(int nArr[][STUDENTCOUNT],int nClassNumber);
＝＝》
void OutputScore(int *nArr[STUDENTCOUNT],int nClassNumber);

后面的第二维的长度 STUDENTCOUNT 必须要有的 ！！

[liuxiang027]

能不能用一个*号做啊
我们只学了一个*
没有学里面用**的~~
先谢了！

[liuxiang027]

把头文件也帮我改一下啊
希望运行没有错误

学了一个星就是学了二个星，一个是指针，二个就是指向指针的指针了

哇，程序太长了，改起来好累的！
蹭点分！
