Else-if ladder execution in C Sharp (C#) - Mini Project: Build & Apply

Else-if Ladder Execution in C#

📖 Scenario: You are building a simple program that checks the temperature and tells the user what kind of weather it is. This is like deciding what to wear based on how hot or cold it is outside.

🎯 Goal: Create a program that uses an else-if ladder to print a message about the weather based on the temperature value.

📋 What You'll Learn

Create an integer variable called temperature with the value 25.

Create an integer variable called hotThreshold with the value 30.

Use an else-if ladder to check the temperature against hotThreshold and other ranges.

Print the correct weather message based on the temperature.

💡 Why This Matters

🌍 Real World

Checking temperature and giving advice is common in weather apps and smart home devices.

💼 Career

Understanding conditional statements like else-if ladders is essential for decision-making logic in software development.

1

Set up the temperature variable

Create an integer variable called temperature and set it to 25.

C Sharp (C#)

int temperature = 25;
// Your code here

Need a hint?

Use int temperature = 25; to create the variable.

2

Add the hot temperature threshold

Create an integer variable called hotThreshold and set it to 30.

C Sharp (C#)

using System;

class Program
{
    static void Main()
    {
        int temperature = 25;
        int hotThreshold = 30;
        // Your code here
    }
}

Need a hint?

Use int hotThreshold = 30; to create the threshold variable.

3

Write the else-if ladder to check temperature

Use an else-if ladder with if, else if, and else to check if temperature is greater than or equal to hotThreshold, between 15 and 29, or below 15. Use Console.WriteLine to print "It's hot!", "It's warm.", or "It's cold!" accordingly.

C Sharp (C#)

using System;

class Program
{
    static void Main()
    {
        int temperature = 25;
        int hotThreshold = 30;

        if (temperature >= hotThreshold)
        {
            Console.WriteLine("It's hot!");
        }
        else if (temperature >= 15 && temperature < hotThreshold)
        {
            Console.WriteLine("It's warm.");
        }
        else
        {
            Console.WriteLine("It's cold!");
        }
        // Your code here
    }
}

Need a hint?

Use if, else if, and else blocks to check the temperature ranges and print messages.

4

Print the weather message

Run the program and print the weather message based on the temperature variable using the else-if ladder you wrote.

C Sharp (C#)

using System;

class Program
{
    static void Main()
    {
        int temperature = 25;
        int hotThreshold = 30;

        if (temperature >= hotThreshold)
        {
            Console.WriteLine("It's hot!");
        }
        else if (temperature >= 15 && temperature < hotThreshold)
        {
            Console.WriteLine("It's warm.");
        }
        else
        {
            Console.WriteLine("It's cold!");
        }

        // Your code here
    }
}

Need a hint?

Run the program to see the message printed based on the temperature.
