##Practice 1: Creating a Simple Student Management System**

Objective: This assignment is designed to help you understand the concepts of classes, objects, constructors, methods, and static members in C#. You will create a simple student management system that demonstrates these concepts.

Assignment Instructions:

1. Create a Class named Student:

   • Define the Student class with the following properties:
     • Name (string) - Name of the student.
     • Age (int) - Age of the student.
     • Grade (double) - Grade of the student.
   • Add a static member to keep track of the total number of students created.

2. Create a Constructor for the Student Class:

   • The constructor should take the student's name, age, and grade as parameters and initialize the properties accordingly.
   • Increment the static member that tracks the number of students whenever a new student object is created.

3. Create a Method in the Student Class:

   • Add a method named DisplayInfo that prints the student's details in a formatted manner.

4. Create a Static Method in the Student Class:

   • Add a static method named DisplayTotalStudents to display the total number of students created.

5. Create an App Class with the Main Method:

   • Create multiple student objects using the Student class.
   • Call the methods of each student object to display their details.
   • Use the static method to display the total number of students.

Expected Output:

Student 1 Information:
Student Name: Alice
Age: 20
Grade: 3.80

Student 2 Information:
Student Name: Bob
Age: 22
Grade: 3.50

Student 3 Information:
Student Name: Charlie
Age: 19
Grade: 3.90

Summary:
Total Students: 3

Concepts Covered:

1. Class: Definition of the Student class with properties.
2. Object: Creation of Student objects (student1, student2, student3).
3. Constructor: Initializes properties and increments the student count.
4. Method: DisplayInfo() method to show student details.
5. Static Member: totalStudents to keep track of all students.
6. Static Method: DisplayTotalStudents() to show the total number of students.

This assignment provides a practical, hands-on approach to understanding how classes, objects, constructors, methods, and static members work together in C#.

Practice 2: Building a Simple Bank Account System**

Objective: This assignment will help you practice defining classes, creating objects, using constructors, properties, and methods in C#. You will create a simple bank account system that demonstrates these concepts.

Assignment Instructions:

1. Create a Class named BankAccount:

   • Define the BankAccount class with the following properties:
     • AccountHolder (string) - The name of the account holder.
     • AccountNumber (string) - The account number (auto-generated or manually set).
     • Balance (double) - The current balance of the account (should only be modified within the class).

2. Create a Constructor for the BankAccount Class:

   • The constructor should take the account holder's name and initial deposit amount as parameters.
   • It should initialize the account holder's name, set an account number, and set the balance to the initial deposit amount.

3. Create Methods in the BankAccount Class:

   • Deposit(double amount): A method to deposit money into the account. Increase the balance by the deposited amount.
   • Withdraw(double amount): A method to withdraw money from the account. Decrease the balance if there are sufficient funds; otherwise, display an error message.
   • DisplayAccountInfo(): A method to display the account holder’s name, account number, and balance.

4. Create an App Class with the Main Method:

   • Create at least two BankAccount objects using the BankAccount class.
   • Use the methods to deposit and withdraw money from the accounts.
   • Display the account information for each account.

Expected Output:

Account 1 Information:
Account Holder: Alice Johnson
Account Number: ACC1000
Balance: $500.00

Account 2 Information:
Account Holder: Bob Smith
Account Number: ACC1001
Balance: $1,000.00

Performing transactions on Account 1...
Successfully deposited $200.00. New balance: $700.00
Successfully withdrew $100.00. New balance: $600.00

Performing transactions on Account 2...
Successfully deposited $300.00. New balance: $1,300.00
Invalid withdraw amount. Please ensure you have sufficient funds.

Updated Account 1 Information:
Account Holder: Alice Johnson
Account Number: ACC1000
Balance: $600.00

Updated Account 2 Information:
Account Holder: Bob Smith
Account Number: ACC1001
Balance: $1,300.00

Concepts Covered:

1. Class: Definition of the BankAccount class.
2. Object: Creation of BankAccount objects (account1, account2).
3. Constructor: Initializes properties with provided values.
4. Properties: Public properties for account holder and private set for account number and balance.
5. Methods: Deposit, Withdraw, and DisplayAccountInfo to perform account operations.

This assignment provides a practical and engaging way for students to practice class, object creation, properties, methods, and constructors in C#.
