Nested loops in MATLAB - Mini Project: Build & Apply

Nested loops

📖 Scenario: You are organizing a small event and want to create a seating chart. You have 3 tables and 4 seats at each table. You want to assign seat numbers for each table.

🎯 Goal: Build a program that uses nested loops to print seat numbers for each table.

📋 What You'll Learn

Create a variable tables with the value 3

Create a variable seats with the value 4

Use nested for loops with variables table and seat

Print the seat assignment in the format: Table X Seat Y

💡 Why This Matters

🌍 Real World

Nested loops are useful when you need to work with grids, tables, or any data with rows and columns, like seating charts, pixel images, or schedules.

💼 Career

Understanding nested loops is important for programming tasks in data analysis, simulations, and automation where you handle multi-dimensional data.

1

Create variables for tables and seats

Create a variable called tables and set it to 3. Create another variable called seats and set it to 4.

MATLAB

Need a hint?

Use = to assign values to variables in MATLAB.

2

Set up nested loops for tables and seats

Write a for loop with variable table that runs from 1 to tables. Inside it, write another for loop with variable seat that runs from 1 to seats.

MATLAB

tables = 3;
seats = 4;
% Your code here

Need a hint?

Use for variable = start:end syntax for loops in MATLAB.

3

Print seat assignments inside nested loops

Inside the inner for loop, use fprintf to print the seat assignment in the format: Table X Seat Y\n where X is table and Y is seat.

MATLAB

tables = 3;
seats = 4;
for table = 1:tables
    for seat = 1:seats
        % Use fprintf to print seat assignment
    end
end

Need a hint?

Use fprintf with %d placeholders for numbers and \n for new line.

4

Run the program to display all seat assignments

Run the program to print all seat assignments for each table and seat using the nested loops and fprintf.

MATLAB

tables = 3;
seats = 4;
for table = 1:tables
    for seat = 1:seats
        fprintf('Table %d Seat %d\n', table, seat);
    end
end
% Run the program

Need a hint?

Check the console output carefully to see all seat assignments listed.
