C++ List orientation
Dec 17, 2015 at 1:12pm UTC
Hi, my name is Karl and working on a sort of "translater program". I am using a swedish word input from the user and a english word input and there after will the program test the user. In windows form.
I'm stuck at the list orientation.
I'm only using one list "glosa" as the input for the swedish and the english words.
I want to send only the swedish words to a textbox and there after let the user to answer the correct putin english word.
The words need to be randomized and there is the problem. How do I randomize the string list without losing the following correct english word which is i+1.
My code:
1#pragma once
#include <list>
#include <ctime>
#include <algorithm>

I would suggest to use a struct for the word combination. Then you may randomize the list without the loss of relation.

How would you go and write that code. It would be better for me to use the randomize of the indexes. How would you use that method?

1struct Word
{
String^ English;
String^ Swedish;
}
typedef List<Word> WordList;
WordList^ glosa;
Now you can easily shuffle the list and get random words.
