What must an object have to be stored in the 'StackTemplate' as designed?

  1. A default constructor

  2. A copy constructor

  3. A virtual destructor

  4. An overloaded '==' operator

The correct answer is: A copy constructor

An object must have a copy constructor to be stored in the 'StackTemplate', as designed. This is because a stack is a last-in-first-out container, which means it removes the most recently added item first. As items are added and removed from the stack, copies of the objects are made and stored in memory. Having a copy constructor ensures that the objects being copied are stored correctly in the stack and that no data or memory is lost. The other options, while important in their own ways, are not necessary for an object to be stored in a stack. A default constructor would only be necessary if the stack was being used to store objects that did not already have pre-existing values. A virtual destructor is not relevant in this context as it deals with the memory management of objects, which is not the concern of a stack. An overloaded '==' operator is used for comparison and does not affect
