Nested loops in C - Mini Project: Build & Apply

Nested loops

📖 Scenario: You are organizing a small event where you want to print a seating chart. The chart shows rows and seats in each row.

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

📋 What You'll Learn

Create two variables for rows and seats per row

Use nested for loops to print seat numbers

Print the seat numbers in the format: Row X Seat Y

💡 Why This Matters

🌍 Real World

Nested loops are useful when dealing with tables, grids, or any situation where you have rows and columns, like seating charts, calendars, or pixel grids.

💼 Career

Understanding nested loops is essential for programming tasks in software development, data processing, and game development where multi-dimensional data is common.

1

Create variables for rows and seats

Create two integer variables called rows and seats_per_row. Set rows to 3 and seats_per_row to 4.

C

// Your code here

Need a hint?

Use int to declare variables and assign the exact values.

2

Set up the outer loop for rows

Add a for loop with variable row that runs from 1 to rows inclusive.

C

int rows = 3;
int seats_per_row = 4;

// Your code here

Need a hint?

Use a for loop starting at 1 and ending at rows.

3

Add inner loop for seats and print seat numbers

Inside the for loop for row, add another for loop with variable seat that runs from 1 to seats_per_row inclusive. Inside the inner loop, print the seat number in the format Row X Seat Y\n using printf.

C

int rows = 3;
int seats_per_row = 4;

for (int row = 1; row <= rows; row++) {
    // Your code here
}

Need a hint?

Use nested loops and printf to print each seat in each row.

4

Print the seating chart

Run the program to print all seat numbers for each row. Use printf as in the previous step to display the output.

C

int rows = 3;
int seats_per_row = 4;

for (int row = 1; row <= rows; row++) {
    for (int seat = 1; seat <= seats_per_row; seat++) {
        // Your code here
    }
}

Need a hint?

Make sure your program prints all rows and seats exactly as shown.
