complete the gaps

the function is supposed to construct a linked list out of
the inputed word

i completed as far as i could.

why i need temp and temp2
??

Code:

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

typedef struct wordStruct{
	char string[256];
	struct wordStruct *next;
} wordStruct;

wordStruct * wordAlloc(char *str){
	wordStruct *temp;
	temp = (wordStruct *)malloc(sizeof(wordStruct));
	temp->next=NULL;
	strcpy(temp->string,str);
	return temp;
} 

wordStruct *insert( wordStruct *head, char *st){
	wordStruct* temp, *temp2;
	
	if(head == NULL) return wordAlloc(st);
	
	if(?? 6 ??|| (?? 7 ?? && ?? 8 ??)){
		temp = ?? 9 ??;
		?? 10 ??;
		return temp;
	}
	
	for(temp=head; temp->next ; temp = temp -> next){
		if(?? 11 ??)break;
		if( ?? 12 ??&& ?? 13 ??)break;
	}	
	
	temp2 = temp->next;
	?? 14 ??;
	?? 15 ??;
	return head;	
}

void main(){	
	char word[256];
	wordStruct *list = NULL;
	
	while(scanf("%s", word)==1)
		list = insert(list, word);				
	. . . .	
}

Looks to me like temp and temp2 are just pointers used for traversing the list, almost like cursors. This certainly looks like an assessment, so please don't look for more specific help...

Usually temp variables are used for swapping / re-organizing elements of a linked list.
However you will get a better answer if those question marks were replaced by real code.

the whole question is about replacing them

how to traverse the list
??

>> void main()

Why is it that you refuse to return an int from main? I've already pointed this out to you no less than three times this week, and I'm sure many others have done as well before. It is an *error*. Period.

>> i completed as far as i could.

Well, if you would actually read and then try to understand responses to some of your previous questions, you might make some progress.

Are you supposed to fill in those blanks ie question marks with code? What are those numbers for then?

yes.
we have a paper and we
say
??1?? : bla bla
??2?? : hhfff

etc..

and we get a grade if we substitute the correct code

I'm betting you get a lousy grade.

>> and we get a grade if we substitute the correct code

I'm pretty sure the "we" is referring to *you*, and not *us*.

yes

so how to use temp and temp 2

if null then it returns the node of the given string

if not then
i would use temp to go to the end of the list and then say
temp->next=wordalloc(st);
return head;

thats it

i dont know why they write so many lines there
?

Why don't you just try writing your own from scratch? Once you have that working, see how your version is different than their version.


Quzah.

i already showed you my solution

and it differs allot
by the number of lines
and the type of them


for example you see that i dont use "if' at all

and it works fine

so how to think of a solution that they are after at

No you didn't. You didn't post anything other than that first post of "Here's some code I was given, I'm supposed to fill in the blanks. Can you do it for me?"


Quzah.

i forgot that its supposed to be sorted by length
and if two words have equal length then by dictionary order

so my solution is no good
