arrayList&[lastIndex]=n;



}

ArrayList* doubleSize(int [] arr&)
{
int [] arr2;= new ArrayList[arr->length*2];
for(int i=0; i<arr.length; i++)
arr2[i]=arr[i];
return arr2;
}

int ArrayList :: deleteLast()

int numDeleted=0;
if(arrayList!=0)
{
numDeleted=arrayList[size];
arrayList[size]=NULL;
if(size<
}
else
{
cout << "Array is empty";
}

return numDeleted;
}

int size()
{
int numElems=0;
for(int i=0;i<arr.length;i++)
