Functions: greeting + farewell

In this C# exercise, you are asked to write a program where the main structure is the Main method. Inside this method, two functions should be called: SayHello and SayGoodbye. The task is to define both functions, which will handle displaying a greeting message and a farewell message respectively. The exercise aims to familiarize you with creating methods in C# and calling them from the main method, helping you understand the basic flow of execution in a function-oriented program.

Functions: Greeting + Farewell

 Objective

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

public static void Main()
{
SayHello();
SayGoodbye();
}

SayHello and SayGoodbye are functions that you must define and that will be called from inside Main.

 Example C# Exercise

 Copy C# Code 
// Importing the System namespace to access basic system functions
using System;

class Program
{
    // Function to print a greeting message
    public static void SayHello()
    {
        // Output a greeting message
        Console.WriteLine("Hello, welcome to the program!");
    }

    // Function to print a farewell message
    public static void SayGoodbye()
    {
        // Output a farewell message
        Console.WriteLine("Goodbye, thanks for using the program!");
    }

    // Main method to call SayHello and SayGoodbye functions
    public static void Main()
    {
        // Call the SayHello function to greet the user
        SayHello();

        // Call the SayGoodbye function to bid farewell to the user
        SayGoodbye();
    }
}

 Output

Hello, welcome to the program!
Goodbye, thanks for using the program!
