• insert

• erase

• display

If the capacity of a static list is fixed, what happens when you try to insert into a full list?

• A new array is created
  

• Program throws an error or terminates
  

• The last element is overwritten
  

• Oldest elements are deleted automatically

Which of the following best describes a static list?

• >>

Which of the following is true about a constructor?

cout << n << " ";

print(n - 1);

}
