Funkcia s rozsahom pola – C / C++ – Fórum – Programujte.com

potrebujem tutu funkciu upravit aby vracala ukazovatel na miesto za poslednim naplnenim prvkom v poli

Inac dost haluzne pouzivas to end, lebo som nenasiel nejak jeho opodstatnenie, radsej by som pouzival velkost pola.Ak som to spravne pochopil tak mas 2 moznosti:

double* fill_array(double * begin)

{

    double temp;

    int i;

    for(i=0;i< Max; i++)

    {

               cout << "Zadajte hodnotu c." << (i+1) << ": ";

               cin >> temp;

               if (!cin)

               {

                        cin.clear();

                        while(cin.get()!='\n')

                                              continue;

                        cout << "Neplatny vstup, zadavanie ukoncene.\n";

                        break;

               }

               else if(temp < 0)

                    break;

               

               *(begin+i)= temp;

    }

    cout << i;

    return (begin+i);

}

int fill_array(double * begin, double **end)

{

    double temp;

    int i;

    for(i=0;i< Max; i++)

    {

               cout << "Zadajte hodnotu c." << (i+1) << ": ";

               cin >> temp;

               if (!cin)

               {

                        cin.clear();

                        while(cin.get()!='\n')

                    break;

               *(begin+i)= temp;

    }

    cout << i;

    *end = begin+i;

    return i;
