Write a program using a class that has array data members NAME, SALARY, YEAR_HIR

Question

Write a program using a class that has array data members NAME, SALARY, YEAR_HIRED. This program will

1) already have the data for 10 records to a random access file

2) allow the user to change the name, salary, or hire_date for a selected record.

3) allow the user to add a record.

Note: The record number is the subscript of the array for NAME, SALARY, DATE_HIRED.  

PLEASE FIRST WRITE A PROGRAM THAT READ THE NAME TO A RANDOM ACCESS FILE AND READS IT  

MAKE SURE THIS WORKS !!

THEN MAKE NAME, SALARY, DATE_HIRED ARRAYS ALREADY BUILT IN THE PROGRAM

THEN MAKE YOUR PROGRAM ALREADY HAVE and CAN READ 10 RECORDS. MAKE SURE THIS WORKS

FINALLY, ALLOW USER TO OUTPUT AND MODIFY SELECTED RECORD. MAKE SURE IT WORKS. YOUR FINAL SUBMISSION MUST COMPILE AND MUST WRITE TO AND READ FROM A RANDOM ACCESS (BINARY) FILE TO GET CREDIT.

Explanation / Answer

Solution:

code:

#include <iostream>
#include <fstream>
#include <iomanip>

using namespace std;

void GetList(ifstream& fileIn, int hiredate[], int employee[], int salary[], int totalRecs);
void menuaction(int hiredate[], int employee[], int salary[], int totalRecs);
void DisplayList(int hiredate[], int employee[], int salary[], int totalRecs);
void sortarray(int hiredate[], int employee[], int salary[], int totalRecs);
void showarray(int hiredate[], int employee[], int salary[], int totalRec);
void UnOrdInsert(int hiredate[], int employee[], int salary[], int totalRecs);

const int MAX_LIST_SIZE = 25;

int main()
{
   // Array of list elements
   int hiredate[MAX_LIST_SIZE];
   int employee[MAX_LIST_SIZE];
   int salary[MAX_LIST_SIZE];
   int totalRecs = 0;

   // Set up file
   ifstream fileIn;
   fileIn.open("employeedata.txt"); //Open The File

   if (fileIn.fail()) // Test for file existence
   {
       cout << "Problem opening file";
       exit(-1);
   }

   ifstream theData;

   GetList(fileIn, hiredate, employee, salary, totalRecs);

   menuaction(hiredate, employee, salary, totalRecs);

}

// This function reads integers from a file and stores the values in
// an array. It returns the loaded array and the number of elements
// in the array

void GetList(ifstream& InFile, int hiredate[], int employee[], int salary[], int totalRecs)
{
   int i = 0;

   // Priming read

   InFile >> hiredate[i] >> employee[i] >> salary[i];

   while (!InFile.eof())
   {
       i++; // Add one to pointer
       // continuation reads
       InFile >> hiredate[i] >> employee[i] >> salary[i];
   }

   totalRecs = i;

}
// This Fuction is the Menu Action
void menuaction(int hiredate[], int employee[], int salary[], int totalRecs)
{

   int choice;

   do
   {
       cout << " Employee Data Menu ";
       cout << "1. List by hiredate ";
       cout << "2. List by employee number ";
       cout << "3. Add employee ";
       cout << "4. TERMINATE SESSION ";
       cout << "Enter your choice: ";

       cin >> choice;
       if (choice >= 1 && choice <= 3)
       {
           switch (choice)
           {
           case 1: DisplayList(hiredate, employee, salary, totalRecs);
               break;
           case 2: sortarray(hiredate, employee, salary, totalRecs);
               showarray(hiredate, employee, salary, totalRecs);
               break;
           case 3: UnOrdInsert(hiredate, employee, salary, totalRecs);
               DisplayList(hiredate, employee, salary, totalRecs);
               break;
      

           }

       }
       else if (choice != 4)
       {
           cout << "The valid choices are 1 through 4. ";
           cout << "Please try again. ";
       }
   } while (choice != 4);

}
//This function writes a list to console output
void DisplayList(int hiredate[], int employee[], int salary[], int totalRecs)
{
   for (int i = 0; i < totalRecs; i++)

       cout << hiredate[i] << " " << employee[i] << " " << salary[i] << " " << endl;
   cout << endl;
}
// This functions Lists the employees by number using sorting
void sortarray(int hiredate[], int employee[], int salary[], int totalRecs)
{
   int temp, temp2, temp3, end;
   for (end = totalRecs - 1; end >= 0; end--)
   {
       for (int i = 0; i < end; i++)
       {
           if (employee[i] > employee[i + 1])
           {
               temp = employee[i];
               temp2 = hiredate[i];
               temp3 = salary[i];
               employee[i] = employee[i + 1];
               hiredate[i] = hiredate[i + 1];
               salary[i] = salary[i + 1];
               employee[i + 1] = temp;
               hiredate[i + 1] = temp2;
               salary[i + 1] = temp3;
           }
       }
   }
}
void showarray(int hiredate[], int employee[], int salary[], int totalRecs)
{
   for (int i = 0; i < totalRecs; i++)
       cout << hiredate[i] << " " << employee[i] << " " << salary[i] << endl;
}

// This function receives an integer, an array containing
// an unordered list, and the size of the list. It inserts
// a new integer item at the end of the list
void UnOrdInsert(int hiredate[], int employee[], int salary[], int totalRecs)
{
   int newint, newint2, newint3;
   totalRecs++; // Increment size of list

   cout << "Insert New Employee HIREDATE:" << endl;
   cin >> newint;
       hiredate[totalRecs] = newint;
   cout << "Insert New Employee ID NUMBER:" << endl;
   cin >> newint2;
       employee[totalRecs] = newint2;
   cout << "Insert New Employee's Salary:" << endl;
   cin >> newint3;
       salary[totalRecs] = newint3;

}
