how delete some record in array ?

New comment
 

Hi guy   i have  one array  with 10 record   but  the  first  and   last  is  empty  i want remove this record how  possible to do that ?

i have crete this  code  but  return array  overflow  therefore  i think  i have  some mistake 

void _CleanArrayIFsomeEmpty(string& Arry[])
{
   string newSymbols[]; // Il nuovo array senza elementi vuoti
   int newSize = 0; // La nuova dimensione dell'array

   // Scorrere l'array e copiare solo gli elementi non vuoti nel nuovo array
   for (int i = 0; i < ArraySize(Arry); i++)
   {
       if (StringLen(Arry[i]) > 0)
       {
           newSymbols[newSize++] = Arry[i];
       }
   }
   
   // Ora newSymbols[] contiene solo gli elementi non vuoti
   ArrayResize(Arry, newSize); // Ridimensiona l'array originale alla nuova dimensione
   for (int Ni = 0; Ni < newSize; Ni++)
   {
       Arry[Ni] = newSymbols[Ni]; // Copia gli elementi non vuoti nell'array originale
   }
}
anyone  can help me ?? thanks 
 
faustf:  i have crete this  code  but  return array  overflow 
  1. Of course, it does. Your newSymbols[] is empty; zero size.
  2. It is unnecessary. 
    void _CleanArrayIFsomeEmpty(string& Arry[])
{
    ArrayResize(array, remove_copy(Arry, 0, ArraySize(Arry), Arry, 0, "") );
}
#define INDEX uint
template<typename Ti, typename To>
INDEX                remove_copy(const Ti& inp[], INDEX iBeg, INDEX iEnd,
                                       To& out[], INDEX oBeg, const Ti& value){
   for(; iBeg != iEnd; ++iBeg){
      if(!(inp[iBeg] == value) )             out[oBeg++] = inp[iBeg];
   }
   return oBeg;
}

 

thanks  for rply but not understund  your code  , i try to test  your  code  but return many error

i correct the code  in this mode  and now  go 


void _CleanArrayIFsomeEmpty(string& Arry[])
{
const string de="";
    ArrayResize(Arry, remove_copy(Arry, 0, ArraySize(Arry), Arry, 0, de) );
}

#define INDEX int

template<typename Ti, typename To>
INDEX remove_copy(const Ti& inp[], INDEX iBeg, INDEX iEnd,
                 To& out[], INDEX oBeg, const Ti& value)
{
    for (; iBeg != iEnd; ++iBeg)
    {
        if (!(inp[iBeg] == value))
            out[oBeg++] = inp[iBeg];
    }
    return oBeg;
}
thanks  so much @William Roeder
 

sorry if i resurected this topic, but i notice the function not work, remaning a blank record

i have array with 10 record , the first and the last is blank(but could be at middle), i want remove the blank record and transform array in size in 8 (and the second record will be a first )

how is possible to do that ???

What do you mean “blank”?

empty, with not  data  inside

Show an example of your code, the function provided does what it is supposed to do. I would guess, there is an error in your code.

i write  up

void _CleanArrayIFsomeEmpty(string& Arry[])
{
const string de="";
Print("cane di pio nono "+ ArraySize(Arry));
    ArrayResize(Arry, remove_copy(Arry, 0, ArraySize(Arry), Arry, 0, de) );
    Print("cane di gesu morto  "+ ArraySize(Arry));
}

#define INDEX int

template<typename Ti, typename To>
INDEX remove_copy(const Ti& inp[], INDEX iBeg, INDEX iEnd,
                 To& out[], INDEX oBeg, const Ti& value)
{
    for (; iBeg != iEnd; ++iBeg)
    {
        if (!(inp[iBeg] == value))
            out[oBeg++] = inp[iBeg];
           //  Print ("cane di dio---->" +inp[iBeg]);
    }
    return oBeg;
}

Sample data?
Print out of journal?
Translation of your text?

Do you expect me to do that all for you, so you get a working code??

Please provide so that I am able to reproduce, without guessing.
 

i  tried  also in this mode but  nothing, return 12 :(((((

// Funzione per rimuovere i record vuoti da un array di stringhe
void RemoveEmptyRecords(string &array[]) {
    string newArray[];
    int newSize = 0;

    for (int i = 0; i < ArraySize(array); i++) {
        if (StringLen(array[i]) > 0) {
            ArrayResize(newArray, newSize + 1);
            newArray[newSize] = array[i];
            newSize++;
        }
    }

    ArrayCopy(array, newArray);
}



// Esempio di utilizzo della funzione
void OnStart() {
    string myArray[] = {"", "AUDUSD", "AUDJPY", "", "NZDJPY", "AUDJPY", "GBPAUD", "EURUSD", "EURAUD", "EURGBP", "EURUSD", ""};
    RemoveEmptyRecords(myArray);
    Print("Array senza record vuoti: ", ArraySize(myArray));
}

 i try also in this mode  but  arraCpy not  copy  :(((

// Funzione per rimuovere i record vuoti da un array di stringhe
void RemoveEmptyRecords(string &array[]) {
    string newArray[];
    
    for (int i = 0; i < ArraySize(array); i++) {
        if (StringLen(array[i]) > 0) {
            ArrayResize(newArray, ArraySize(newArray) + 1);
            newArray[ArraySize(newArray) - 1] = array[i];
        }
    }
    ArrayFree(array);
     ArrayResize(array,ArraySize(newArray),ArraySize(newArray)); 
    
    ArrayCopy(newArray, array);
}
