Question

I need help finishing this question up:

I understand I need to add a destructor for aptr. I am puzzled by the rest

template <class T>
void SimpleVector<T>::push_back(T element){

   // Allocate a new array 1 element larger than the current one.

   T* aptrp1 = new T[arraySize + 1];

   // Copy the current array contents to the new array
   for (int i = 0; i < arraySize; i++)
{
aptr[i] = aptrp1[i];
}

   // Copy the argument value to the end of the array

   // Delete the old array (aptr)

   // Make aptr point to the new array

   // Adjust arraySize to reflect the extra element you just added
}

Answer 1

If you have any doubts, please give me comment...

template <class T> void SimpleVector<T>::push_back(T element) {

// Allocate a new array 1 element larger than the current one.

T *aptrp1 = new T[arraySize + 1];

// Copy the current array contents to the new array

for (int i = 0; i < arraySize; i++) {

aptrp1[i] = aptr[i];

}

// Copy the argument value to the end of the array

aptrp1[arraySize] = element;

// Delete the old array (aptr)

delete aptr;

// Make aptr point to the new array

aptr = aptrp1;

// Adjust arraySize to reflect the extra element you just added

arraySize += 1;

}
