Question

Im getting a segmentation fault when trying to display an element of type (int)

template <class T>
void Lista<T>::imprimir()
{
    NodoL *ptr = new NodoL;
    ptr->sig = pri->sig;
    cout << *ptr->sig->elem; //THIS DISPLAYS CORRECTLY
    cout << *ptr->sig->sig->elem; //SEGMENTATION FAULT
}

Answer 1

Are you sure sig is not NULL ?

template <class T>
void Lista<T>::imprimir()
{
    NodoL *ptr = new NodoL;
    ptr->sig = pri->sig;
    cout << *ptr->sig->elem; //THIS DISPLAYS CORRECTLY
    if(ptr->sig == NULL || ptr->sig->sig == NULL)
       return;

    cout << *ptr->sig->sig->elem; //SEGMENTATION FAULT
}
