String comparison in MATLAB - Mini Project: Build & Apply

String comparison

📖 Scenario: You are working on a simple program to check if two words are the same. This is useful when you want to compare user input with a correct answer or check if two labels match.

🎯 Goal: Build a MATLAB script that compares two strings and tells if they are exactly the same or not.

📋 What You'll Learn

Create two string variables with exact values

Create a variable to hold the comparison result

Use the strcmp function to compare the two strings

Print the comparison result

💡 Why This Matters

🌍 Real World

String comparison is useful in many programs where you need to check if user input matches expected answers, like password checks or form validations.

💼 Career

Understanding string comparison is important for software testing, data validation, and building interactive applications.

1

Create two string variables

Create two string variables called word1 and word2 with the exact values 'hello' and 'Hello' respectively.

MATLAB

% Your code here

Need a hint?

Use single quotes to create strings in MATLAB, like word1 = 'hello';

2

Create a variable for comparison result

Create a variable called areEqual to store the result of comparing word1 and word2 using the strcmp function.

MATLAB

word1 = 'hello';
word2 = 'Hello';
% Your code here

Need a hint?

Use strcmp(word1, word2) to compare the two strings exactly.

3

Check the comparison result

Use an if statement to check if areEqual is true. Inside the if, create a variable called message with the value 'The words are the same.'. Otherwise, set message to 'The words are different.'.

MATLAB

word1 = 'hello';
word2 = 'Hello';
areEqual = strcmp(word1, word2);
% Your code here

Need a hint?

Use if areEqual to check the boolean and assign message accordingly.

4

Display the result message

Use the disp function to print the value of the message variable.

MATLAB

word1 = 'hello';
word2 = 'Hello';
areEqual = strcmp(word1, word2);
if areEqual
    message = 'The words are the same.';
else
    message = 'The words are different.';
end
% Your code here

Need a hint?

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