c++ - Translation/Transliteration problems -

i working on translation/transliteration program, reads english story, , translates elvish, using english/elvish dictionary. after code shown below, explain error receive.

i have lot of code, not sure if should post all, post think should sufficient. apologies if code seems bizarre - beginner.

there main file, header file 2 classes: translator , dictionary, , cpp file implement class functions.

i have constructor reads in dictionary file dictfilename , copys english words englishword, , elvish words elvishword:

translator::translator(const char dictfilename[]) : dict(dictfilename) {       char englishword[2000][50];      char temp_eng_word[50];     char temp_elv_word[50];     char elvishword[2000][50];     int num_entries;      fstream str;      str.open(dictfilename, ios::in);     int i;      while (!str.fail())       {        (i=0; i< 2000; i++)           {           str>> temp_eng_word;           str>> temp_elv_word;           strcpy(englishword[i],temp_eng_word);           strcpy(elvishword[i],temp_elv_word);            }          num_entries = i;        }        str.close();  } 

in main file, english lines read toelvish function, , tokenized array of words, temp_eng_words.

within toelvish function, calling function; translate, reads in temp_eng_words , supposed return elvish words:

char translator::toelvish(char elvish_line[],const char english_line[])   {     int j=0;      char temp_eng_words[2000][50];     //char temp_elv_words[2000][50]; not sure if need      std::string str = english_line;     std::istringstream stm(str);     string word;     while( stm >> word) // read white-space delimited tokens 1 one      {        int k=0;        strcpy (temp_eng_words[k],word.c_str());         k++;      }         (int i=0; i<2000;i++) // error: out_s not declared in scope     {     dictionary::translate (out_s,temp_eng_words[i]); // error relates line     }  } 

this translate function:

char dictionary::translate (char out_s[], const char s[]) {   int i;       (i=0;i < numentries; i++)      {         if (strcmp(englishword[i], s)==0)         break;       }          if (i<numentries)         strcpy(out_s,elvishword[i]); } 

my problem when run program, error '*out_s not declared in scope*'.

if have read of this, thanks; suggestions/clues appreciated. :)
