Need Help Scrambling Words for a Game.

Hello! I am trying to make a unscrambling game. I need to know how to scramble words that I read from a file? Also how would I loop the same word back the prompt if I unscramble the word wrong?

Code:

---

#include <iostream>
using namespace std;
#include <fstream>
#include <cstring>
#include <cstdlib>


int main()
{
        ifstream list;
        char word[15], name[15], choice, answer[15];

       
        list.open ("list.txt");

        do       
        {
               
                list >> name;
                cout << "Unscramble the following word: " <<name << endl;
                cout << "Write your answer: ";
                cin >> answer;

                while(strcmp(answer, name) == 0)
                {
                        cout << "Great!\n";
                        break;
                }
                while(!strcmp(answer,name) == 0)
                {
                       
                        cout <<"Try again.\n";
                        break;
                }
               
                if(strcmp(answer,name) == 0)
                {
                        cout << "Do you want to play again [y/n] ";
                        cin >> choice;

                        if(choice == 'n' || choice == 'N')
                                {
                                        cout <<"Bye!\n";
                                        break;
                                }
                }
               

       
        }while (!list.eof());

       
        return 0;
       

}

Your two inner while() loops are worthless. What's the point of immediately break-ing? while() loops are loops, and loops are meant to have the possibility of looping. Your inner while() loops will only 'loop' once. Your program structure need to be re-thunk.

As for scrambling words, the easiest way would be to select two characters at random from the word, and swap them. Repeat a few times, maybe 5, 10, the strlen() of the word...

(This is probably better situated in the C++ Forum as well. Please be sure to post in the correct location, help will come quicker!)

Moved to correct forum

Once the word is scramble how do you unscramble the word back into the original order?

Why would you need to do that? You know the original word.

Its easy to unscramble back if the original list has a pattern or if it is sorted.

I am a real noob to programming. When the word is scramble, the word variable changes, so I need to know how to unscramble the word into the original order so the program can compare the users input to the original word to check if the user unscramble the word correctly. Bye the way I am using the swap function to scramble the words. Also for example the char variable word[15] hold the a set of letters and char original, so how do you correctly make "original=word" without getting an error?

Why don't you make two copies of the array. One will contain all of the words. The other would correspond to the scrambled words. That way unscrambledArray[5] would correspond to scrambledArray[5].

Use strings, and copy into a char array. Then randomize your char array.
When the user inputs the guessed word, input it to a string. And compare the user string with the original string.

Like so:

Code:

---

#include <iostream>
#include <string>

using namespace std;

int main()
{

        string example;
        int string_length; //Int to hold string length so you know how much to copy.
        char randomized_word[40];

        memset(randomized_word, '\0', 40); /*This 'clears' everything
        in the memory space of the char array. Other wise, if you copy
 less characters than total array you will have a bunch of garbage */
       
        example = "word or sentence to be randomized";

        string_length = example.length(); // Returns string length and places it variable

        example.copy(randomized_word,string_length); /*This is the bread and butter,
 first variable in the () is the array name, then coma then the array length */       


        cout << randomized_word; //You still have to randomize this array, but I will leave that up to you.
But now you have a string (to compare easily, with the
 == operator to what the user inputs. And an array to randomize to output.


        return 0;


}

*edit*
It took a bunch of edits, but I think I finally fixed the spacing error (the forum screwed up my spacing in program and made the page really freakin wide!).

Thank you so much Loctan, the "example.copy(randomized_word,string_length);" becaue I never heard of it until know and that is just what I needed.

Okay now I need help on how to loop the same question with the same exact word if the user enters the wong scrambled word.

Nevermind, I just figured it out! Thanks alot guys!

Okay, what would I use if I have to select a word randomly from a list?
