使用链接列表的C错误

Question

我和我的朋友正在开发一个像鸭鸭一样的项目，我们在使用我们需要使用的链表时遇到了问题。从我可以告诉的几个测试输入中，当我们插入名称（字符串）时，似乎存在问题，它没有正确保存到LL，并且因为当我们尝试打印它时崩溃。您可以在此处访问项目信息：http://tinyurl.com/DuckDuckBoot。

样本输入和输出如下：

**Input**
2
3
Bob
Cody
John
2 2
8
Carol
Casey
Nick
Kirsten
Ben
Bo
Billy
Heather
3 4
**Output:**
Game 1:
Cody

Game 2:
Billy
Bo
Carol
Kirsten
Nick

以下是代码：

    temp -> next = Start;

    scanf("%d", &NumberOfGames);
