i want to create a program that translates a sentance in english to another language

[jerger]

I want to help teach to a minority group in Milwaukee, so I want to create a dictionary program that translates a sentence (like a homework problem or teacher instructions), from English into Hmong.

I have one Idea, and that is to have an English text file of all the A-words, then a Hmong text file of the proper translations. Each text file would have the same amount of lines, with one english word per line, then translated to hmong. Would it be even possible to..

1. user inputs question, "Describe the holocaust"
2. describe is looked in the d text (like if d, search d.txt), then the word is found. then it either compares it to a translation txt (like hmong-d.txt), spitting out the word. then it would prompt to the next word to translate, one line at a time.

A different way was to have 1 giant text file for each letter. like look up "albino", when it finds the word in the a a-dictionary, it searches for the albino string, then finds the comma, then spits out the word/words after the comma. would this be possible as well? which method is easiest for someone that hasn't c++ in a few years?

so far I have a useless code typed up. i just want to start simple getting a-words to work, then get more complex from there. once i have a start i can go with it. please help me, i would love to reach the needs of my esl students who could use this greatly in the US.

summary,i want to take a line of words, compare each word to a specific dictionary, then output one line at a time, the translation. thank you so much!

this code is not correct:

#include <iostream> // I/O
#include <fstream> // file I/O
#include <iomanip> // format manipulation
#include <string>

//This program will hopefully translate english to hmong
using namespace std;
string english; //declare english word to translate
string search; //what to search

int main()
{

cout << "Type the english words here, then press enter. Make sure to copy the words correctly. If you need to spell check use www.google.com" ;
cin >> english;

ifstream myFile;
myFile.open ("c:\\eAh.txt") ;

string* search = english; //search using input
int offset; // where it was found (or not (-1))
if ((offset = line.find(searc h, 0)) != string::npos) {
cout << "found '" << search << "' @ offset " << offset << endl;
}

return 0;
}

Quick couple of questions....
Is this code compiling?
If not, what error messages do you get?
If so, how do you know it isn't working (ie does it crash, or does it give bad ouput and if so what is the output)?

I think that that is the easiest way to do it instead of having to look through two different files for each word. How big do you expect these files to get?

string* search = english; //search using input
int offset; // where it was found (or not (-1))
if ((offset = line.find(search, 0)) != string::npos) {
cout << "found '" << search << "' @ offset " << offset << endl;
 

You never defined "line" and I dont think that you need a search variable.

retract that........

hmm... how should i define line? i kind of found this on the internet, where they didn't define the line function. can anyone help with that?

i basically will have 100 words in a textfile for the letter a... (or 200, if it includes both languages seperated by , commas)

so i want it to search through a.txt for "apple" then find apple, and state

apple = koj thoj (made that up)

hmm... maybe i could replace the ,'s in my .txt files to have " = " instead, so it can simply just output the line? that would simplify my code.

so... search textfile of a words, find "apple", then stop when it finds the space (so if it finds a word like applelot (made up) it doesnt create a false positive, then prints out apple = koj thoj.

ps: i'll make sure to give you guys credit in the code. this is a freeware program for students, i want them to have access to this stuff !

I believe the line is a string.....
While you could read the whole file into the string, you could also consider parsing the file line by line.
Provided each of your line has similar structure (and starts with the word to translate), and assuming that these are listed alphabetically, you could try to implement a binary search to speed the effort up as the file gets large (which it will if you plan to store an entire dictionary)

(I'm pretty sure a file has a getline function (or similar))

any examples?

i need an example for the function, and what to do with the input.

should i have my text be one text file for a-english words, or two text files with one with english and another with the same amount of lines/line numbers for the different language?

if one textfile for a-words, should it be...

apple = koj thao

apple, koj thao

with the first example, i could simply return the entire line which would help my students. so if i had several dictionaries it would be like this

****
input your sentence in english: I love you.

i = kuv
love = hlub
you = koj

would you like to translate more words? y/n

if i could get a head start, it would help if i could at least get an example of taking an input that is a string, one word, then searching it in a text file, once it is found in the text file, spit it back out with something like love = hlub. the text file will be alphabetical even if it is tedious for me. that way in the future i could increase efficiency.

from here i hope i can figure out how to search multiple words in multiple textfiles using the if statements and your guy's help with the function... so eventually the search can occur in a generic file like trans[a].txt or trans[b].txt where the letter for the dictionary would be based on the first letter of the english word from the cin input. that means eventually i would need to create a string for each english word, and store it temporarily, then compare each one and spit it out one at a time. or in a simple way, word one>function>sp it out, word two>function>sp it out

first few lines from my a .txt file:

Abdomen = Plab mog
Able = Rooj
Able = Ua tau
Abortion = Rho menyuam tawm
About = Li ntawm
Above = Saum toj

the description here is similiar in context, but it would not compile for me:(

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
 
int main () {
  string line;
cout << "Type the english words here, then press enter. Make sure to copy the words correctly. If you need to spell check use www.google.com";
cin >> english;
 
  ifstream myFile ("c:\\eAh.txt");
  if (myFile.is_open())
  {
    while (! myFile.eof() )
    {
      getline (myFile,line);
      if(strncmp(line, english, englis.length())
      {
         cout <<"Match found"<< line;
      }
    }
    myFile.close();
  }
 
  else cout << "Unable to open file"; 
 
}

would be one way to try (assuming the english word is the first item in a row of the file you are trying to parse)

well that is a start.. but a cin>> just restates the entire .txt file dictionary...

anything i could put at the end of a line, to indiciate... stop typing?

maybe an if statement so it only says one word.... then in my txt file have a period? so that at the end of the sentance like

love = hlub.

the line code stops printing out lines? or some better looking character ?
