Objective
1. Define a method called SayHello that takes a string parameter (a name) and prints a personalized greeting message using that name.
2. Define a method called SayGoodbye that prints a farewell message.
3. The Main method should call SayHello with a string parameter (e.g., "John") and then call SayGoodbye.
4. Run the program to observe the greeting and farewell messages displayed on the screen.
Write a C# program whose Main must be like this:
public static void Main()
{
SayHello("John");
SayGoodbye();
}
Example C# Exercise
Show C# Code
using System;
class Program
{
// Main method where the program execution begins
public static void Main()
{
// Call the SayHello function with "John" as the parameter
SayHello("John");
// Call the SayGoodbye function
SayGoodbye();
}
// Function to print a personalized greeting message
public static void SayHello(string name)
{
// Display a hello message with the provided name
Console.WriteLine($"Hello, {name}! Welcome to the program!");
}
// Function to print a goodbye message
public static void SayGoodbye()
{

Console.WriteLine("Goodbye, thank you for using the program!");
}
