Instructor Information Management System

Overview

A C++ program to manage and display instructor details using object-oriented programming. The program allows users to input instructor details, validates the input, and displays the filtered and validated information. It demonstrates the use of constructor overloading to initialize objects with default or user-provided values.

Features

• Defines an Instructors class with private attributes (Name, Age, and Salary) and public methods to set and retrieve these attributes.
• Includes constructor overloading:
  • Default Constructor: Initializes attributes with default values (Name = "Unknown", Age = 0, Salary = 0).
  • Parameterized Constructor: Initializes attributes with user-provided values and validates them.
• Validates user input for:
  • Name: Only alphabetic characters and spaces are allowed.
  • Age: Must be between 26 and 59 years.
  • Salary: Must be between 7001 and 29999 EGP.
• Creates two instances of the Instructors class in the main() function:
  • One using the default constructor.
  • One using the parameterized constructor.
• Prints instructor details using the print() method.
• Implements a destructor to print a farewell message when an object is destroyed.

Code Structure

• Instructors Class:

  • Attributes:
    • Name: Stores the instructor's name (default: "Unknown").
    • Age: Stores the instructor's age (default: 0).
    • Salary: Stores the instructor's salary in EGP (default: 0).
  • Constructors:
    • Default Constructor: Initializes attributes with default values.
    • Parameterized Constructor: Validates and initializes attributes with user-provided values.
  • Methods:
    • SetName(string n): Validates and sets the instructor's name. Filters out non-alphabetic characters.
    • GetName(): Returns the instructor's name.
    • SetAge(int x): Validates and sets the instructor's age.
    • GetAge(): Returns the instructor's age.
    • SetSalary(int s): Validates and sets the instructor's salary.
    • GetSalary(): Returns the instructor's salary.
    • print(): Prints the instructor's details.
    • ~Instructors(): Destructor that outputs a farewell message.

• main() Function:

  • Creates two instructor objects:
    • No1: Initialized using the default constructor.
    • No2: Initialized using the parameterized constructor.
  • Prompts the user to input details for each instructor.
  • Validates and sets the attributes using the SetName, SetAge, and SetSalary methods for No1.
  • Uses the parameterized constructor to validate and initialize attributes for No2.
  • Calls print() to display each instructor's details.

How to Run the Program

1. Compile the program using a C++ compiler:

   g++ instructors.cpp -o instructors

2. Run the compiled executable:

   ./instructors

3. Follow the prompts to enter instructor details.
4. The program will display the instructor details after validation.

Sample Output

Enter the name of first instructor: Ma7m5d  
Enter the age of first instructor: 30  
Enter the salary of first instructor: 15000  
The instructor name is Mamd with age 30 years old and salary is 15000 EGP.  
Bye Bye Mamd

Enter the name of second instructor: J@ne D0e  
Enter the age of second instructor: 20  
Invalid age. Using default age (25).  
Enter the salary of second instructor: 5000  
Invalid salary. Using default salary (7000).  
The instructor name is Jne De with age 25 years old and salary is 7000 EGP.
Bye Bye Jne De  

Potential Improvements

1. File Handling: Save instructor data to a file for later retrieval.
2. Input Validation Enhancements:
   • Allow special characters (e.g., hyphens or apostrophes) in names if necessary.
   • Provide more detailed error messages for invalid inputs.
3. User Interface:
   • Add a menu-driven interface for easier interaction.
   • Allow users to edit or delete instructor records.
4. Data Persistence:
   • Use a database to store and manage instructor data.
5. Additional Attributes:
   • Add more attributes like Department, Email, or Phone Number.
6. Search and Filter:
   • Implement functionality to search for instructors by name, age, or salary.
7. Error Handling:
   • Handle exceptions for invalid input types (e.g., non-integer input for age or salary).

Dependencies

• C++ Standard Library (<iostream>, <string>).
• A C++ compiler (e.g., g++).
