If-elseif-else statements in MATLAB - Mini Project: Build & Apply

If-elseif-else statements

📖 Scenario: You are creating a simple program to check the temperature and give advice on what to wear.

🎯 Goal: Build a MATLAB script that uses if-elseif-else statements to print clothing advice based on the temperature.

📋 What You'll Learn

Create a variable temperature with a specific value

Create a variable cold_threshold with a specific value

Use if-elseif-else statements to check the temperature against thresholds

Print the correct advice message based on the temperature

💡 Why This Matters

🌍 Real World

Checking temperature and giving clothing advice is common in weather apps and daily planning tools.

💼 Career

Understanding conditional statements is essential for programming logic in many software development jobs.

1

DATA SETUP: Create the temperature variable

Create a variable called temperature and set it to 15.

MATLAB

temperature = 0; % Your code here

Need a hint?

Use the assignment operator = to set temperature to 15.

2

CONFIGURATION: Create the cold threshold variable

Create a variable called cold_threshold and set it to 10.

MATLAB

temperature = 15;
cold_threshold = 0; % Your code here

Need a hint?

Set cold_threshold to 10 using the assignment operator.

3

CORE LOGIC: Use if-elseif-else to check temperature

Write an if-elseif-else statement that checks if temperature is less than cold_threshold. If yes, assign advice the value 'Wear a coat.'. Else if temperature is less than 20, assign advice the value 'Wear a jacket.'. Otherwise, assign advice the value 'Wear a t-shirt.'.

MATLAB

temperature = 15;
cold_threshold = 10;
% Your code here

Need a hint?

Use if, elseif, and else keywords with conditions and assign advice accordingly.

4

OUTPUT: Display the advice

Use disp to print the value of the variable advice.

MATLAB

temperature = 15;
cold_threshold = 10;

if temperature < cold_threshold
    advice = 'Wear a coat.';
elseif temperature < 20
    advice = 'Wear a jacket.';
else
    advice = 'Wear a t-shirt.';
end
% Your code here

Need a hint?

Use disp(advice) to show the advice on the screen.
