Answer:
Here is the updated code for the `arrayListType` class with the abstract function `min` added:
```cpp
class arrayListType
{
public:
virtual int min() const = 0;
//other member functions
};
```
And here is the implementation of the `min` function in the `unorderedArrayListType` class:
```cpp
class unorderedArrayListType : public arrayListType
{
public:
int min() const override
{
int minVal = list[0];
for (int i = 1; i < length; i++) {
if (list[i] < minVal) {
minVal = list[i];
}
}
return minVal;
}
//other member functions
};
```
And here's an example program that uses the `min` function:
```cpp
#include <iostream>
#include "arrayListType.h"
#include "unorderedArrayListType.h"
using namespace std;
int main()
{
unorderedArrayListType intList(25);
int number;
cout << "Enter 8 integers: ";
for(int i = 0; i < 8; i++)
{
cin >> number;
intList.insertEnd(number);
}
cout << endl;
intList.print();
cout << endl;
cout << "The smallest number in intList: " << intList.min() << endl;
return 0;
}
```
Assuming that the `arrayListType` and `unorderedArrayListType` header and implementation files are properly included and compiled, this program should output the smallest number in the list.
