Switch statement execution in C Sharp (C#) - Mini Project: Build & Apply

Switch Statement Execution

📖 Scenario: Imagine you are building a simple program that tells the day type based on the day number. This is like a small calendar helper that says if a day is a weekday or weekend.

🎯 Goal: You will create a program that uses a switch statement to print whether a day number (1 to 7) is a weekday or weekend.

📋 What You'll Learn

Create an integer variable called dayNumber with a value from 1 to 7.

Use a switch statement on dayNumber.

Print "Weekday" for days 1 to 5.

Print "Weekend" for days 6 and 7.

Print "Invalid day" for any other number.

💡 Why This Matters

🌍 Real World

Switch statements help programs make decisions based on different values, like menus, commands, or day types.

💼 Career

Understanding switch statements is important for writing clear and efficient code in many software development jobs.

1

Create the day number variable

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

C Sharp (C#)

# Your code here

Need a hint?

Use int dayNumber = 3; to create the variable.

2

Start the switch statement

Write a switch statement using dayNumber as the expression.

C Sharp (C#)

int dayNumber = 3;

// Start the switch statement on dayNumber
# Your code here

Need a hint?

Use switch (dayNumber) { } to start the switch.

3

Add cases for weekdays and weekends

Inside the switch, add cases for 1 to 5 that print "Weekday", cases for 6 and 7 that print "Weekend", and a default case that prints "Invalid day".

C Sharp (C#)

int dayNumber = 3;

switch (dayNumber)
{
    // Add cases for 1 to 5 to print "Weekday"
    // Add cases for 6 and 7 to print "Weekend"
    // Add default case to print "Invalid day"
# Your code here
}

Need a hint?

Group cases 1 to 5 together to print "Weekday". Group 6 and 7 to print "Weekend". Use default for invalid days.

4

Run and display the output

Run the program and observe the output printed by the switch statement.

C Sharp (C#)

int dayNumber = 3;

switch (dayNumber)
{
    case 1:
    case 2:
    case 3:
    case 4:
    case 5:
        System.Console.WriteLine("Weekday");
        break;
    case 6:
    case 7:
        System.Console.WriteLine("Weekend");
        break;
    default:
        System.Console.WriteLine("Invalid day");
        break;
}

// Run the program to see the output
# Your code here

Need a hint?

The output should be Weekday because dayNumber is 3.
