Well, I never was able to 100% walk backwards through my double-linked list, but I do appreciate all your help. I submitted my code as is and my professor sent me his solution. I don't want to post...

you know, shouldn't walking backwards in a double linked list be just as easy as walking forward?? arrgh

Well, I use pWalker in the Count_Words() function to traverse the linked list forward (and count the number of words in the lists). So at the end of that function, pWalker is Null because that is...

Ok, when I traverse the list forward, I stop when pWalker = NULL. The last line of code that does this is: pWalker = pWalker->next . pWalker->next is null, so pWalker is set to NULL. So, in order...

hmm, it should actually display the word after it prints out the number of words from that list. Well, I will have to keep playing with it tomorrow. Thanks again.

Hi Ancient Dragon...I appreciate your help. I have to run now, but I will check back in tomorrow and continue working on this. Thank you!

Hmm, I will have to re-read my material then. I thought you had to allocate memory. :-(

When I add cout << "test" to see where the crash occurs, it occurs during this line:

cout << pCurrent->newWord << " ";

Oh ok.... (and letter[] is defined globally).

Ok, I was trying that, but still couldn't get it right. The head pointer is letter[count].

Here is what I tried that causes a crash:


word *pCurrent;

pCurrent = pWalker;

...

Ok, would I just need to make a new pointer like:

word *pCurrent;

?

Hello, I am having some trouble traversing backwards through a double linked list. Basically this program pulls words from a text file (I have attached the file I am using), corrects the words and...

Hello Duoas....so I took your advice and played around some with my code, and it seems to be working better now (at least the words are added to the top of the linked list). The program is suppose to...

Thank you, it does help. I will try the changes tonight after work. As for the array of linked lists....yeah, that is what we are required to do.

Hope your headache feels better soon!

Thanks...

Hello, I am having trouble creating a double linked list within an array of pointers. Right now actually, I am just trying to make a linked list. Line 267 is where I get a complier error. I...

Thank you! I will try that.

Hello,

I wanted to post some code with line numbers and can't figure out how to do this. I searched the FAQ, and tried [list=1], but it didn't turn out right. I would hate to manually insert line...

Currently I am a CS student but am thinking about switching to CIS. Honestly, I don't want to be a programmer. I am grateful to learn the concepts, and (sometimes) enjoy the challenge. But I can't...

Ok, thank you! I tried this code to initialize all 26 pointers, and then printed them to the screen to check. They are printed out as '0'. I did have change the current->head = NULL to current = NULL...

Hmmm, I wonder if I could use the first block of code that initializes one linked list as one function, and then call that function within a for loop that runs through the 26 pointers. Hmmm.

Ok, so I need to initialize the double linked list. This is the code I wrote so far that worked:


wordList* Initialize_Lists()
{

// function to create list

char ch;

Hello, I have to create a double linked list array of pointers for the alphabet (one pointer per letter).

Ok, so I tried starting by creating a double linked list:

I don't know....I lived in Germany the past 3 years (in Dresden) and it was mildly interesting to the people there. Dresden did have an American football team, but soccer was just so much more loved....

Thanks Ancient Dragon,

(I will number my lines from now on!)...

I changed the pointer to be passed as a reference. That definitely helped read in the data from the file. My output still isn't...

Hi Wenny86....lots of ppl here are very helpful, but only if you show effort to solve your problem first. Try writing out your algorithms and some code and posting specific problems, and ppl usually...

Hello,

I am trying to call two functions: one that pulls data from a file and stores into a linked list, and one that displays this data to the screen. I pulled my code out of the functions and...

Thank you. That did the trick.

Hello,

I would like to be able to declare a filename as a global constant (so I can change the input file easily), which seems to be a simple thing to do, but I can't seem to get it to work.

I...

Ok, thank you.

Hello,

The uppercase 'A' to 'F' relate to the seats per row (there are 6 seats per row).

I tried placing & before row....the PLANE.BIN file is now created....I just have to get the program to...

Hello,

Well, I wasn't defining "seats" again as a local variable. I was just setting the size of the array (I thought that would be ok since I left out the 'int' before the variable inside the...

Hello, I am trying to write data to a binary file. The function runs (the cout << "TEST" shows me that my loop is running the correct amount of times), but after the program comes to the end, it...

Thank you. That did the trick. I didn't know that all components in a string are characters, even if they are numbers.....which makes since. That helped me solve a problem I was having during error...

Ok, I know you aren't suppose to (or can't) do comparions on arrays such as, if (x < y), when both x and y are single dimensional arrays. But what about if you have a string and want to compare one...

Loop is working now. I had to move the do{ after the very first cin >> studentId;. The program needed to calculate the length of the studentId each time a new studentId was entered in. I still have...

Well, your tip is working. I am finding problems I didn't know existed. I will post again once I figure it out in case someone is interested. Thanks again.

Ok, thank you....I am trying that now.

How's it going NicAuf? Were you able to figure out your code? Salem wants you to show all your code (if you are having problem with the die rolling, then you have more code than you are showing)....

I ran that example program on that webpage, and it did change the random number (after running the program twice). It seems you have to change the srand value from srand ( time(NULL) ); to srand (1);...
