Question

For the array version of the stack, write a new member function that returns the maximum number of items that can be added to the stack without stack overflow.

Answer 1

To determine the maximum number of items that can be added to an array-based stack without causing overflow, subtract the current number of elements (size) from the total capacity of the stack.

Step-by-step explanation:

A stack implemented using an array has a fixed size, which is determined at the time the stack is created. To write a member function that returns the maximum number of items that can be added without causing a stack overflow, we need to consider two values: the total capacity of the stack and the current number of items in the stack.

The function could look like this:

int Stack::maxAddable() {
return capacity - size;
}

Here, 'capacity' refers to the maximum number of items that the stack can hold, and 'size' is the current number of items in the stack. This function simply subtracts the size from the capacity to determine how many more items can be added to the stack without exceeding its fixed size and thus causing an overflow.
