【程序72】:创建一个链表。
1.程序分析:
2.程序源代码:
/*creat a list*/
#include "stdlib.h"
#include <stdio.h>
struct list
{ int data;
struct list *next;
};
typedef struct list node;
typedef node *link;
viod main()
{ link ptr,head;
int num,i;
ptr=(link)malloc(sizeof(node));
ptr=head;
printf("please input 5 numbers==>\n");
for(i=0;i<=4;i++)
{
scanf("%d",&num);
ptr->data=num;
ptr->next=(link)malloc(sizeof(node));
if(i==4) ptr->next=NULL;
else ptr=ptr->next;
}
ptr=head;
while(ptr!=NULL)
{ printf("The value is ==>%d\n",ptr->data);
ptr=ptr->next;
}
}

【程序73】:反向输出一个链表。
1.程序分析:
2.程序源代码:
/*reverse output a list*/
#include "stdlib.h"
#include <stdio.h>
struct list
{ int data;
struct list *next;
};
typedef struct list node;
typedef node *link;
viod main()
{ link ptr,head,tail;
int num,i;
tail=(link)malloc(sizeof(node));
tail->next=NULL;
ptr=tail;
printf("\nplease input 5 data==>\n");
for(i=0;i<=4;i++)
{
scanf("%d",&num);
ptr->data=num;
head=(link)malloc(sizeof(node));
head->next=ptr;
ptr=head;
}
ptr=ptr->next;
while(ptr!=NULL)
{ printf("The value is ==>%d\n",ptr->data);
ptr=ptr->next;
}}

【程序74】:连接两个链表。
1.程序分析:
2.程序源代码:

struct list
{ int data;
struct list *next;
};
typedef struct list node;
typedef node *link;
link delete_node(link pointer,link tmp)

else /*delete the other node*/

return pointer;
}
}
void selection_sort(link pointer,int num)
{ link tmp,btmp;
int i,min;
for(i=0;i<num;i++)
