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

Nested loop execution

📖 Scenario: You are organizing a small event where you want to greet each guest with a special message for each day of the event. You will use nested loops to print these greetings.

🎯 Goal: Build a program that uses nested loops to print a greeting message for each guest for each day of the event.

📋 What You'll Learn

Create an array of guest names

Create an integer variable for the number of days

Use nested for loops to print greetings for each guest for each day

Print the greeting messages in the format: "Hello, [Guest]! Welcome to day [Day]!"

💡 Why This Matters

🌍 Real World

Nested loops are useful when you need to perform repeated actions inside other repeated actions, such as scheduling, seating arrangements, or generating tables.

💼 Career

Understanding nested loops is essential for programming tasks like data processing, simulations, and building user interfaces that require multiple levels of iteration.

1

Create the guest list

Create a string array called guests with these exact names: "Alice", "Bob", "Charlie".

C Sharp (C#)

// Your code here

Need a hint?

Use string[] guests = { "Alice", "Bob", "Charlie" }; to create the array.

2

Set the number of days

Create an integer variable called days and set it to 3.

C Sharp (C#)

string[] guests = { "Alice", "Bob", "Charlie" };
// Your code here

Need a hint?

Use int days = 3; to set the number of days.

3

Write nested loops for greetings

Use nested for loops with variables i and j to iterate over guests and days. Inside the inner loop, create a string variable message with the value: $"Hello, {guests[i]}! Welcome to day {j + 1}!".

C Sharp (C#)

string[] guests = { "Alice", "Bob", "Charlie" };
int days = 3;
// Your code here

Need a hint?

Use two for loops: outer loop for guests, inner loop for days. Use string interpolation for the message.

4

Print the greeting messages

Inside the inner for loop, add a Console.WriteLine(message); statement to print each greeting message.

C Sharp (C#)

string[] guests = { "Alice", "Bob", "Charlie" };
int days = 3;
for (int i = 0; i < guests.Length; i++)
{
    for (int j = 0; j < days; j++)
    {
        string message = $"Hello, {guests[i]}! Welcome to day {j + 1}!";
        // Your code here
    }
}

Need a hint?

Use Console.WriteLine(message); inside the inner loop to print each message.
