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

While loop execution model

📖 Scenario: You are helping a cashier count the number of customers entering a store until the store closes.

🎯 Goal: Build a program that uses a while loop to count customers until a closing time is reached.

📋 What You'll Learn

Create an integer variable called customers starting at 0

Create an integer variable called closingTime set to 5

Use a while loop with the condition customers < closingTime

Inside the loop, increase customers by 1 each time

Print the final number of customers after the loop ends

💡 Why This Matters

🌍 Real World

Counting customers or events until a certain limit is reached is common in stores, games, or data processing.

💼 Career

Understanding loops is essential for automating repetitive tasks and controlling program flow in software development.

1

Create the initial customer count

Create an integer variable called customers and set it to 0.

C Sharp (C#)

// Your code here

Need a hint?

Use int customers = 0; to start counting customers from zero.

2

Set the closing time

Create an integer variable called closingTime and set it to 5.

C Sharp (C#)

int customers = 0;
// Your code here

Need a hint?

Use int closingTime = 5; to set the limit for counting customers.

3

Write the while loop to count customers

Use a while loop with the condition customers < closingTime. Inside the loop, increase customers by 1.

C Sharp (C#)

int customers = 0;
int closingTime = 5;
// Your code here

Need a hint?

Use while (customers < closingTime) and inside the loop write customers++; to add one each time.

4

Print the final customer count

Write a Console.WriteLine statement to print the value of customers after the loop ends.

C Sharp (C#)

int customers = 0;
int closingTime = 5;
while (customers < closingTime)
{
    customers++;
}
// Your code here

Need a hint?

Use Console.WriteLine(customers); to show the final count.
