    Question please help..linked list homework assignment due tomorrow..

    hey im trying to read a sequence of strings from the user and store them in different nodes..my code reads the line and stores it as a whole sentence , how do i split the line into individual strings and store them into different nodes ? if i use strtok it only stores the first word and ignores the rest..please help!

    Code:
            getline(words)
            p=(Node *) malloc(sizeof(Node));
    	strcpy(p->word,words);
    	p->next = head;
    	head = p;
    Code:
     char *getline( char *text)
    {
    	if( fgets( word, 128, stdin ) == NULL ) return NULL;
    	if( ( temp = strchr( words, '\n' ) ) )
    		*temp = 0;
    	else while( getchar() != '\n' );
    	return words;
    }

    Use a loop where you call strtok() with NULL as the first parameter. Do this until you get a NULL back from strtok() [whcih means "no more to find"].

    thanks i used a while loop instead
    Code:
            tok = strtok(word, " ");
    	while (tok != NULL) {
    	p=(Node *) malloc(sizeof(Node));
        	strcpy(p->word,tok);
    	p->next = head;
    	head = p;
    	tok = strtok(NULL," ");}
