C语言课程设计~~~ 要求编写一段程序,题目是《校际运动会管理系统》
我这是源代码已经调试过了,在VC++上运行成功了。

C语言程序设计 中国铁道出版社的 课后习题答案?
一.
1.错(链表可以不是)
2.错(顺序适合查找较多的数据结构,链表适合插入删除较多的数据结构)
3.错(有可能连续)
4.错(int a[2][3]中,元素为整型)
5.对.
二.
1.B
2.C
三.
1.D
2.D
3.C(这里是要找到长度为m的链表的尾节点)
四.
1.S1语句是让p指向尾节点(因为while退出的条件是p-next,说明此时p-next为空)
2.S2语句是在链表尾插入q(p-next=q),并让q成为链表尾节点(q-next=NULL)
3.(a1,a2,a3,...an,q)
(注,这里的L是不带头节点的单链表,故第一个节点就是该元素的第一个节点)
另外,虚机团上产品团购,超级便宜
