本文介绍了一个简单的链表实现过程，包括链表的创建、打印及转换为字符数组的方法。通过C语言，演示了如何从标准输入读取字符并构建单向链表，最后输出链表内容。

#include <stdio.h>
#include <stdlib.h>

struct s_list
{
	char c ;
	struct s_list *next;

};

void creat_list(struct s_list **headp)
{
	char ch;
	struct s_list * loc_head = NULL,*tail;
	if((ch = getchar()) == EOF);
	else
	{
		loc_head = (struct s_list *)malloc(sizeof(struct s_list));
		loc_head -> c = ch;
		tail = loc_head;
		while((ch = getchar()) != EOF)
		{
			tail -> next = (struct s_list *)malloc(sizeof(struct s_list));
			tail = tail -> next;
			tail -> c = ch;
		}
		tail -> next = NULL;
	}
	*headp = loc_head ;

}

void print_list(struct s_list *headp)
{
	while(headp != NULL)
	{
		printf("%c",headp->c );
		headp = headp -> next;
	}
	printf("\n\n");

}

void print_array(struct s_list *headp)
{
	int i,tot;
	struct s_list * p = headp;
	char * ch;
	for(tot = 1; p->next != NULL; tot++)
	{
		p = p->next;
	}
	p = headp;
	ch = (char *)malloc(tot*sizeof(char));
	for(i = 0 ; i < tot ;i++)
	{
		ch[i] = p->c;
		p  = p -> next;
	}
	ch[i] = '\0';
	puts(ch);
}
int main()
{
	struct s_list *head = NULL;
	creat_list(&head);
	print_list(head);
	print_array(head);
	return 0;
}
