how can I delete the elements of array after read it in C++? -

array<personne> personnes;   while (in) {     personne newpersonne;     in >> newpersonne;     if (in.eof()) break;     personnes.add(newpersonne);     if (personnes.size() > 1) {         (int = 0; < personnes.size() - 1; ++i)              (int j = + 1; j < personnes.size(); ++j) {                 string typerelation = personnes[i].gettyperelation(personnes[j]);                 if (typerelation != "")                     cout << personnes[i].getnom() << " , " << personnes[j].getnom() << " " << typerelation << endl;                 if (j ==  personnes.size() -1){                     personnes.delete(i); //doesn't work well, want delete first element when finishing copmarison withe other elements.                  }                 }     } } 

i want delete first elements of array when second boucle reaching end

a couple of killers in tableau::delete method:

the function not compile because of use of delete keyword function's name

elements[index+1] allow reading elements[nbelements] may or may not out of array's bounds, 1 more intended.

try instead:

template <class t>  void tableau<t>::remove(size_t index) // size_t unsigned , prevents input of                                        // negative numbers. 1 less test required.                                       // nbelements should made unsigned match                                       // function name changed legal. {        assert(index < nbelements); // ensures nbelements > 1                                  // nbelements-- not go out of bounds     nbelements--; // moved above loop because index+1 grab last element     for( ; index < nbelements; index++) // no need have i. index     {         elements[index] = elements[index+1];     } }
