Simple C# Program with Functions

This C# program demonstrates the use of functions by defining two simple methods: SayHello and SayGoodbye. The Main method calls these functions sequentially to display a greeting message and a farewell message. This program serves as a basic introduction to how functions can be defined and called in C#.

Functions in C#

Objective

1. Define a method called SayHello that prints a greeting message to the console.
2. Define a method called SayGoodbye that prints a farewell message to the console.
3. The Main method must call these functions in the specified order: first SayHello, then SayGoodbye.
4. Run the program to see the output of both functions.

Write a C# program whose Main must be like this: 

public static void Main()

{

  SayHello();

  SayGoodbye();

}

Example C# Exercise

 Copy C# Code 
using System;

class Program
{
    // Main method where the program execution begins
    public static void Main()
    {
        // Call the SayHello function
        SayHello();

        // Call the SayGoodbye function
        SayGoodbye();
    }

    // Function to print a greeting message
    public static void SayHello()
    {
        // Display a hello message on the console
        Console.WriteLine("Hello, welcome to the program!");
    }

    // Function to print a goodbye message
    public static void SayGoodbye()
    {
        // Display a goodbye message on the console
        Console.WriteLine("Goodbye, thank you for using the program!");
    }
}

 Output

Hello, welcome to the program!
Goodbye, thank you for using the program!
