如何在链接列表中输入单词？

Question

I had a doubly linked list capable of holding characters in each node. This is what I do to input characters to each node.

printf("Enter string of characters for the list: ");
scanf("%s",s);
for(i=0;s[i]!='\0';i++)
    Insert(s[i],&Header1);

Now i wish to modify the list to store words in each node.The input provided by the user is a sentence. How do i make sure each word(separated by space) gets into a node of the list?

Answer 1

while ( sscanf( sentence, "%s", &node_value ) == 1 )
{
  //Call to insert into your list goes here
  //Each pass node_value will be the next word
}

NOTE: You will have to pass node_value by value into your list, otherwise all your values will be the same reference!

Answer 2

char *word;
while (NULL != (word = strtok(s, " ."))) {
    Insert(word, &Header1);
}

Answer 3

You need to modify the node as
struct node {
node *prev;
char *data;
node *next;
}

and change the scanf to ' fgets .
I have declared data as a char * , so you cannot use strncpy. If you want to copy the string(instead of assigning pointer), then you should malloc the data.
