Question

1. Do not change anything in the supplied code below that will be the Ch12_Ex9.cpp except to add documentation and your name.
2. Please use the file names listed below since your file will have the following components:
   Ch12_Ex9.cpp given file

   //Data: 18 42 78 22 42 5 42 57

   #include <iostream>
   #include "unorderedArrayListType.h"

   using namespace std;

   int main()
   {
   unorderedArrayListType intList(25);

       int number;

       cout << "Enter 8 integers: ";

       for (int count = 0; count < 8; count++)
   {
   cin >> number;
   intList.insertEnd(number);
   }

       cout << endl;
   cout << "intList: ";
   intList.print();
   cout << endl;

       cout << "The smallest number in intList: "
   << intList.min() << endl;
   system("pause");
   return 0;
   }

   arrayListType.h
   arrayListType.Imp.cpp
   unorderedArrayListType.h
   unorderedArrayListTypeImp.cpp

3. Add the function min as an abstract function to the class arrayListType to return the smallest element of the list.
4. Also, write the definition of the function min in the class unorderedArrayListType and write a program to test this function.

Answer 1

EXPLANATION : We first declare an abstract function in the class arrayListType. Since, min() being an abstract function we need to define it in the class unorderedArrayListType. You need to add the lines of code written by me in your cpp files and run it to check the min() function.

class arrayListType {
public:   
int min(); //Declaring an abstract function in the class arrayListType
}

#include <iostream>
#include <algorithm>

#include "unorderedArrayListType.h"

#include arrayListType.h
using namespace std;
class unorderedArrayListType : arrayListType {
public:   

int unorderedArrayListType::min() //Defining the function min in the class unorderedArrayListType
{
   int* i1;
   i1 = std::min_element(List+1, List+8); // Finding the minimum value in the given list which consists of 8 elements.

   return *i1; // Returning the minimum value in the list.
}

int main()
{
unorderedArrayListType intList(25);

    int number;

    cout << "Enter 8 integers: ";

    for (int count = 0; count < 8; count++)
{
cin >> number;
intList.insertEnd(number);
}

    cout << endl;
cout << "intList: ";
intList.print();
cout << endl;

    cout << "The smallest number in intList: "
<< intList.min() << endl;
system("pause");
return 0;
}

}

THANKS,

PLEASE UPVOTE THE ANSWER AS IT WOULD BE OF GREAT HELP TO ME.
