Hello the replacement function doesn't work in the previous code Maybe it works better that way! The rest of the errors I don't understand.

for the rest of the errors I don't understand how to modify the program without making a class or a structure.
but the program is recursive, as long as it has no solution it replaces the current word and tries to position it in the grid. It makes mistakes while checking the box where it places the letter of the word. there are variables declared that aren't used, but I didn't clean it up. It's my draft style ;)

for the rest of the errors

Exactly what errors are you talking about?

I don't understand how to modify the program without making a class or a structure.

More functions would probably be a good place to start. Also getting rid of all those horrible global variables and constructs like: goto placing_word; would probably be a good idea as well.

but the program is recursive,

I don't see any "recursion" in your last couple of posts, perhaps you could point out where the recursion is happening.

as long as it has no solution it replaces the current word and tries to position it in the grid. It makes mistakes while checking the box where it places the letter of the word.

What "mistakes" are you talking about.

If you are getting compile/link errors post them exactly as they appear in your development environment, and it would probably be better if you posted the complete program that generates the "mistakes" or "errors" and provide any and all input you supplied, and show the output you desire based on the input you supplied.

oneidacharisse (81)
It's when the word crosses two other words it makes mistakes more often. Why is it that when I check what's in the grid and which char is present, he still places the word?

in this loop for example :

 
 
if (grid[x][y + j] == empty || grid[x][y + j] == word[j])


to finish on the style, I have nothing against refinement but if it's making classes and structures, it doesn't respect my initial idea !

I don't know the variable writing standards you use. I learned at home, sorry.

"Recursion (adjective: recursive) occurs when a thing is defined in terms of itself or of its type.Recursion is used in a variety of disciplines ranging from linguistics to logic.The most common application of recursion is in mathematics and computer science, where a function being defined is applied within its own definition. While this apparently defines an infinite number of instances ..."

I think the fact that I'm testing the words and replacing it and going back to the beginning of the main function is kind of recursive.

The dictionary is a text file a list of words like this one but longer (about 22000 words):

Aaron
lowering
lower
abandonment
abandoning
gives up
gives up
abandoned
abandoned
give up
give up
dropouts

The complete program is as shown above, and my environment is dev c++ on windows 7. I have no compilation error, what I want is to cross a maximum of words in a grid with as few letterless boxes as possible. A sort of crossword puzzle.

Propose code! Because to say that my code is sketchy, I get it now. But it doesn't matter since I don't know the coding standards lol

Then I suggest you review your practices and stop using some of the poor practices you are now using.

Using goto is considered an extremely bad practice in most cases and should be avoided. Learn to use other more acceptable loop constructs instead. Also more functions would probably help avoid the "need" for goto.

Using global variables is also a bad practice and should be avoided whenever possible. Learn to pass the required variables to and from your functions as required. Using global variables make it much harder to troubleshoot logic problems because where a global variable changes values can be difficult to spot.

Don't let "being self taught" be an excuse to fail to learn from your mistakes.

but if it's making classes and structures, it doesn't respect my initial idea !

Well maybe you need to rethink your initial idea. Using structures and classes often greatly simplify things. IMO, if you're going to write C++ code you shouldn't be ruling out one of C++'s greatest assets.

I think the fact that I'm testing the words and replacing it and going back to the beginning of the main function is kind of recursive.

In C++ recursion usually means that you have a function that calls itself. Iteration is when you use a loop (in this case the horrible goto) to repeat parts of a function.

But it doesn't matter since I don't know the coding standards lol

What's so funny about lack of knowledge? What have you done to try to solve this failing?

Propose code!

This is your program, I have made suggestions but you don't seem to interested to implement the suggestions so I don't know what more I can do to help.


Have you run the program with your debugger, single stepping through the program watching the various variables as you step?



Looking at your partial dictionary I do see some problems, there appears to be "words" that contain spaces won't that cause problems.
oneidacharisse (81)
So keep your value judgments, please. With classes and structures I can't do half of what I do with what bothers you. And if helping people for you means creating a new topic with unusable code for those who are trying to learn, look for the meaning of the word pedagogy. Then if the small elite who make the code treat those who try as you do, if they don't come to tell us about the incapacity of some to adapt, the maladjusted are those who lack humility.
dhayden (5795)
It's a good idea to clean up compiler warnings. That way if a new one appears and indicates an actual bug, it will stand out. For example, PlaceHorizontal and PlaceVertical should return void instead of int, and loop counters that compare to vector::size() should be unsigned instead of int

can_place_v and can_place_h have an unused parameter (id_word)

randomword(): Consider reading the dictionary into a vector at the beginning of the program. That would probably save time. Even a huge dictionary will fit in just a few megabytes. Google's list of the 10,000 most popular English words is just 75kb. 350,000 words take just 3.7MB.

If you don't want to read the dictionary into memory, move the call to transform() outside the loop. You only need to transform the word that you selected.

Instead of writing:
1
2
3
 
            temp_word0 = words_vect[k - 1];
            temp_word1 = words_vect[k];
            std::string intersec = find_intersection(temp_word0, temp_word1);

just pass the words to find_intersection by value. Then you can do
std::string intersec = find_intersection(words_vect[k-1], words_vect[k]);

I don't see any code to verify whether a word will run off the end of the grid.

BUG #1: You will only try to place a word horizontally if it can ALSO be placed vertically:
1
2
3
4
5
6
7
8
9
10
11
12
13
 
            if (score_v == current_word.length()) {
                if (k % 2 == 0) {
                    ...
                    goto placing_word;
                }
            } else {
                ...
               goto back;
            }
            // This code is reached only when score_v==current_word.length() && k%2 != 0
            //if the horizontal score of the position is equal to the size of the word
            if (score_h == current_word.length()) {
                if (k % 2 != 0) {


When you place a word, you push each letter's coordinate into coord_x and coord_y. But you check to place them, you look at coord_x[k-1] where k is the number of the word being placed. This doesn't make sense to me, especially considering that you never clear coord_x and coord_y. You should check your logic for these values.

BUG #2: You're getting horizontal and vertical confused. In PlaceVertical() you have:
if (grid[x + j][y] == empty || grid[x + j][y] == word[j]) {
and in can_place_v you have:
if (grid[x][y + j] == empty || grid[x][y + j] == word_letter) {

And similarly for PlaceHorizontal()/can_place_h()

The first coordinate is the row number (vertical) and the second is the column (horizonal)

Hello, thank you indeed I had a confusion between the note and the placement it was reversed.

And for this line, when I do as you advise it mixes up the letters of the word, I don't understand why. The word is unreadable at the end of the function.
 
 
std::string intersec = find_intersection(words_vect[k-1], words_vect[k]);



"I don't see any code to verify whether a word will run off the end of the grid."

I don't understand what you're trying to tell me.


My logic is this: coord_x[k-1] and coord_y[k-1] are the coordinates of the word placed before, having an alternation of even and odd numbers I thus make sure not to place the following word in the same way as the previous one. Assuming that I have the same number of coordinates as the word placed, by taking the index k I make sure to find a match.

Sorry I didn't take the order of your ideas/questions to answer you.

I suspect you only did half of what I suggested. You missed this part:
pass the words to find_intersection by value


The words get scrambled because find_intersection sorts the letters in each word. You need to change it to pass the arguments by value:
1
2
 
std::string find_intersection(std::string first, std::string second)
{ ...

You have a 25x25 grid of letters. You place words in the grid. What prevents you from placing. say, "birthday" horizontally at position row=2,col=20? If you put it there, the word will "spill out" beyond column 25.

My logic is this: coord_x[k-1] and coord_y[k-1] are the coordinates of the word placed before
But you push x,y for each letter in the word. So if you place "birthday" at (8,5), then coord_x contains {8, 8, 8, 8, 8, 8, 8, 8 } and coord_y contains {5, 5, 5, 5, 5, 5, 5, 5 }. You need to push back just one number to each inside PlaceHorizontal and PlaceVertical.

Because if I don't remember both coordinates, I can't place the next word.

And to replace the word if it doesn't fit how do I do with a function to be able to go back to the search for an intersection letter without goto I do k-1 and let the for arrive at the end?

std::string replace_word(std::string & current_word)
{
                                //replaces the word and goes back to the beginning of the checks.
					int rand3 = random(100, 20000);
				std::string replacement = randomword(rand3);

				std::replace(words_vect.begin(), words_vect.end(), current_word, replacement);
}


Otherwise it doesn't actually work, it's because my scoring loop was wrong that he managed to come back. In this loop:

And for the debug I tried with dev c++ but it makes a mistake and shuts down the compiler.

It probably crashes because you've defined replace_word as returning a string but it returns nothing. Change it to return void.

When I run it in a debugger, it crashes in can_place_v() because x == -3. As I've said before, you really need to ensure that you don't try to place a word outside the grid.

remove srand() from replace_word().

In fact, for now I'd comment out the call to srand(). That way you can debug the program with the same set of words each time. I'd also print the grid after each word is placed. With those and a few other changes for debugging, I have this code. Note that I replaced the initialization of grid() with a call to memset() in main to reduce the size of the code.

Here is the start of the output that I get. Your output will be different because you're using a different dictionary and your rand() may be different from mine:

 Testing word 2/10
 Current v score 6/6
 Prev word aadefinrss Current word almous
-----
Placing almous vertically at 8,7


Some immediate problems to consider:
- Why didn't it place "afraidness" so it overlaps "alertest"? It overlaps with 'a', 'e', 'r', and 's'.
- When placing almous, why is afraidness() all scrambled? Ah. I see that you STILL haven't done what I suggested for find_intersection(). Pass the parameters by value instead of by reference.

Ok thank you very much, I had modified the code to make it work better but I'll start from your code again.

and for find_intersection you mean like in this example:
1
2
3
4
5
6
 
std::string do_something ( std::string inval )
{
   std::string return_val;
   // ... do stuff ...
   return return_val;
}


without the & sign ?

which would be:

1
2
3
4
5
6
7
8
9
10
 
std::string find_intersection(std::string first, std::string second)
{
    std::sort(first.begin(), first.end());
    std::sort(second.begin(), second.end());
    int length = std::min(first.length(), second.length());
    std::string result(length, ' ');
    std::set_intersection(first.begin(), first.end(), second.begin(), second.end(),
			  result.begin());
    return result;
}


and the function call would be the same ?
I'll work on it. Thanks again.

regarding find_intersection, yes, that's what I mean.

BTW, I find it really confusing dealing with the grid when the first dimension is the row number and the second is column, but you use variables x and y for the first and second indexes. That means x is the row number, which increases in the vertical direction, and y is the column, which increases in the horizontal direction. You might want to change your variables to "row" and "column" or r and c to make it easier to understand.

Hi, okay, I'll do it next time. Here I cleaned up the useless variables and made the corrections based on your code. I left the random to see. The program still crashes despite the fact that in the placement test functions I take care of the grid dimension to avoid in getting out. I hope that I have taken into account everything you told me. I'm learning a lot, that's great, thanks again. Here is my corrected code:
