For loop execution model in C Sharp (C#) - Mini Project: Build & Apply

For loop execution model

📖 Scenario: Imagine you are organizing a small event and want to count how many guests will attend. You have a list of guest names, and you want to print each name one by one using a loop.

🎯 Goal: You will create a list of guest names, set up a counter, use a for loop to go through each guest, and print their names one by one.

📋 What You'll Learn

Create a list of guest names with exact values

Create an integer variable to count guests

Use a for loop with a counter variable to iterate over the list

Print each guest name inside the loop

Print the total number of guests after the loop

💡 Why This Matters

🌍 Real World

Counting and listing items is common in many programs, like showing guest lists, product inventories, or task lists.

💼 Career

Understanding how for loops work with lists is a basic skill needed for software development, data processing, and automation tasks.

1

Create the guest list

Create a List<string> called guests with these exact names: "Alice", "Bob", "Charlie", "Diana", "Ethan".

C Sharp (C#)

// Create the guest list with exact names
// Your code here

Need a hint?

Use List<string> and initialize it with the exact names inside curly braces.

2

Create a guest counter

Create an integer variable called guestCount and set it to guests.Count to store the number of guests.

C Sharp (C#)

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List guests = new List { "Alice", "Bob", "Charlie", "Diana", "Ethan" };
        // Create guestCount variable
        // Your code here
    }
}

Need a hint?

Use int guestCount = guests.Count; to get the number of guests.

3

Use a for loop to print each guest

Use a for loop with an integer variable i starting at 0, running while i < guestCount, and increasing i by 1 each time. Inside the loop, print the guest name at index i from guests.

C Sharp (C#)

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List guests = new List { "Alice", "Bob", "Charlie", "Diana", "Ethan" };
        int guestCount = guests.Count;
        // Use a for loop to print each guest
        // Your code here
    }
}

Need a hint?

Use for (int i = 0; i < guestCount; i++) and inside the loop print guests[i].

4

Print the total number of guests

After the for loop, print the total number of guests using Console.WriteLine with the exact text: Total guests: followed by the value of guestCount.

C Sharp (C#)

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List guests = new List { "Alice", "Bob", "Charlie", "Diana", "Ethan" };
        int guestCount = guests.Count;
        for (int i = 0; i < guestCount; i++)
        {
            Console.WriteLine(guests[i]);
        }
        // Print total guests
        // Your code here
    }
}

Need a hint?

Use Console.WriteLine("Total guests: " + guestCount); after the loop.
