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;
}

i made your changes, similiar issue occurs. do we have to define the function at the bottom of the code? what would i do for that? this is what i got

errors:
37 C:\hmong dictionary.cpp no matching function for call to `strncmp(std::s tring&, std::string&, <unknown type>)'

note C:\temp\Dev-Cpp\include\str ing.h:51 candidates are: int strncmp(const char*, const char*, size_t)

code:


#include <iostream>

#include <fstream>

#include <string>

using namespace std;



int main () {

string line;
string english;


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);

// int strncmp(line, english, english.length( ));

{
if (strncmp(line, english, english.size))
cout <<"Match found"<< line;

}

}

myFile.close();

}



else cout << "Unable to open file";


}

btw do you sleep? hahaha you are a great help

This is generally considered bad practice, but you could try adding a cast to see if whether that's the problem:

strncmp(line, english, (size_t)(englis h.length()));
or
strncmp(line, english, (size_t)(englis h.size()));

:(

that just causes more problems err. hehe

[DeMan]

I'll have a think about it.....
you can use
strcmp(String1, String2)
which doesn't need length (the one with length is considered safer because people find it harder to manipulate into overflowing/injecting format strings etc (because you limit the length), for a local app (and certainly for now), it may be worth trying it. )

12 C:\hmong dictionary.cpp expected constructor, destructor, or type conversion before '(' token

12 C:\hmong dictionary.cpp expected `,' or `;' before '(' token


if i actually put the ; in after this, it recreates both the new and old error messages! errr it makes no sense

[DeMan]

you could also use

 
int pos = line.find(english);
if(pos!= string::npos)
{
    //pos is the position of the begining of the word you are searching for in the
    // string from the dictionary.  If you have set up the file to have each line
    //  word, definition
    // then pos must be 0 to be a valid word (otherwise you may get strange 
    // results - eg looking for "at" would leave pos= 1 in a string beginning "cat")
}

This error is at line 12 (which I suspect is where you declare the strings)

this just makes me more confused haha. it compiles, but just couts nothing and then closes
