Question

In C++ write a class. The requirements for the class are define as followings:

• Class StudentBubbleSorter – This class will have the following methods with their signatures as listed below:
  • Sort() – This method will receive an array of Student records to be sorted. It will sort the records by Student ID(s). It will also return the sorted array of Student records.
  • PrintRecords() – This method will receive an array of Student records. It will print out the information of each Student record.

Hi,

I am putting the required code for couple of functions of the class below. In the code, a class student is created with Student_ID as variable, On the basis of ID, bubble sort is implemented. You can always add more variables in class student according to records data available. I have temporarily created record using create_array method in the code itself. You can send your array of students record if available to the sort function directly. students_record[] is my records array. Please refer code below.

******************* Code Begin ********************

#include<iostream>
#include<conio.h>
#include<string>
#define MAX 50
using namespace std;

class student
{
public:
   int Student_ID;
};

class StudentBubbleSorter
{
public:
   void Sort(student students_record[], int count) //Here function receiving array of student records and total count of records // for sorting
   {
       for (int i = 0; i < (count - 1); i++)
       {
           for (int j = 0; j < (count - i - 1); j++)
           {
               if (students_record[j].Student_ID > students_record[j + 1].Student_ID)
               {
                   student temp = students_record[j];
                   students_record[j] = students_record[j + 1];
                   students_record[j + 1] = temp;
               }
           }
       }
   }

   void PrintRecords(student students_record[], int count) //printing student records
   {
       cout << "Here is the sorted record date => \n";
       int i;
       for (i = 0; i < count; i++)
       {
           cout << students_record[i].Student_ID << "\n";
       }
   }

};

int create_array(student students_record[]) //This function is only for creating temporary students record data.
{

   int count, i;
   cout << "Enter no of students you want to insert";
   cin >> count;
   for (i = 0; i < count; i++)
   {
       cout << "Enter student ID => ";
       cin >> students_record[i].Student_ID;
   }

   return count; //Returning total no of records in array.
}
int main()
{
   student students_record[MAX]; //Array of students record. Keeping max size of array to 50
   StudentBubbleSorter obj; //Object of class StudentBubbleSorter

   int count = create_array(students_record); //Creating temporary data for the code. If you have actual array ready, you // can skip this function call and directly send array to the sort function.
    obj.Sort(students_record, count); //Calling sort function and sending records array as well as total count of records.
   obj.PrintRecords(students_record, count); //Calling print function to print records.

  
   return 0;
}

That's all for now.
