assign values to struct string[2]

jwalpole (2)
I have googled and have not found anything relating to this, or am just looking for the wrong thing.

I have a struct 
1
2
3
4
5
6
7
8
9
10
11
12
 

enum LANG_ID_TYPE {
  FIRSTLANG, //0
  ENGLISH = FIRSTLANG, //0
  SPANISH, //1
  LASTLANG = SPANISH //1
  };

typedef struct {
  int          LitId ;
  std::string  Literals[LASTLANG+1] ;
  } LiteralStruct ;


and when used statically is populated like so:
1
2
3
4
5
6
7
8
9
10
 
const int NUM_SORT_STRINGS = 23;

const LiteralStruct SortStrings [ NUM_SORT_STRINGS ] = {
  { 0, //error type id
      "All", //english
      "Todos" //spanish},
  { 1,
      "Horse",
      "Caballos" }
}


and accessed as:
 
 
TheString = ErrMsgs[ ErrorId ].Literals[ LangId ].c_str() ;


I am trying to do this dynamically by reading a file, binary so users cannot modify. Right now I am not worried about the binary part. I just need to get this populated.

This is what I have tried:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

20
21
22

void LoadCSVTranslations::readStringValuesToMap() {
    int delimeterPos;
    std::string translatedValueString,translationKeyname;
    ifstream litfile;
    litfile.open("..//..//langlits.dat", ios::in);    
    int i = 0;
    string   line;
    string   outstr;

    LiteralStruct ErrMsgs[ MAX_ERR ] = {} ;
    int t = FIRSTLANG;
    while(getline(litfile, line)){
        delimeterPos = line.find(',');
        translationKeyname = line.substr(0, delimeterPos);
        translatedValueString = line.substr(delimeterPos+1);
      
        if(atoi(translationKeyname.c_str()) == 38 &&  t < LASTLANG)
            t++;   
        
        if( atoi(translationKeyname.c_str()) >= 0 && atoi(translationKeyname.c_str()) <= 38)
        {
            ErrMsgs[ atoi(translationKeyname.c_str()) ].LitId = atoi(translationKeyname.c_str());
            if( t > 0 && t < LASTLANG+1)
                ErrMsgs[ atoi(translationKeyname.c_str()) ].Literals->append(",");
            
            ErrMsgs[ atoi(translationKeyname.c_str()) ].Literals->append("\"" + translatedValueString + "\"");
            
        }     
    }//endwhile
    
    litfile.close();
}


I have also tried:
1
2
 
 ErrMsgs[ atoi(translationKeyname.c_str()) ].Literals[ t ].append("\"" + translatedValueString + "\"");
 ErrMsgs[ atoi(translationKeyname.c_str()) ].Literals[ t ] = "\"" + translatedValueString + "\"";


I figured this would work and populate the Literals[2] (LASTLANG+1). Am I missing something or misunderstanding std::string name[] and how it works?

So what's the problem? Are you getting compiler errors? Does it not work properly?

sorry. the problem is that when t changes from 0 to 1 and I do a watch on ErrMsgs, it only shows the recent assignment and there is not array for me to click on as I would expect.

Even though when I hover over Literals it does show it as an array Literals[ 2 ] it would appear that Literals[ t ] doesn't work to assign value to new array value.
