Dynamic memory allocation (heap) in Compiler Design - Mini Project: Build & Apply

Understanding Dynamic Memory Allocation (Heap)

📖 Scenario: Imagine you are designing a simple program that needs to store information about books in a library. The number of books is not fixed and can change while the program runs. To handle this, you will learn how dynamic memory allocation works using the heap.

🎯 Goal: You will build a conceptual model of dynamic memory allocation on the heap by creating a list of book titles, setting a limit for maximum books, adding new books dynamically, and finally marking the end of the list.

📋 What You'll Learn

Create a list called books with three initial book titles exactly: '1984', 'Brave New World', and 'Fahrenheit 451'.

Create a variable called max_books and set it to 5 to represent the maximum number of books allowed.

Add two more book titles 'The Handmaid's Tale' and 'The Road' to the books list dynamically.

Add a special string 'END' at the end of the books list to mark the end of allocated memory.

💡 Why This Matters

🌍 Real World

Dynamic memory allocation is used in programs where the amount of data changes during execution, such as managing lists of users, files, or game objects.

💼 Career

Understanding heap allocation is essential for software developers, especially those working with low-level languages or performance-critical applications.

1

Create the initial list of books

Create a list called books with these exact book titles: '1984', 'Brave New World', and 'Fahrenheit 451'.

Compiler Design

# Create the initial list of books
# Your code here

Need a hint?

Use square brackets [] to create a list and separate items with commas.

2

Set the maximum number of books allowed

Create a variable called max_books and set it to the number 5 to represent the maximum books allowed in memory.

Compiler Design

books = ['1984', 'Brave New World', 'Fahrenheit 451']
# Set max_books to 5
# Your code here

Need a hint?

Just assign the number 5 to the variable max_books.

3

Add two more books dynamically

Add the book titles 'The Handmaid's Tale' and 'The Road' to the books list using the append() method.

Compiler Design

books = ['1984', 'Brave New World', 'Fahrenheit 451']
max_books = 5
# Add two more books dynamically
# Your code here

Need a hint?

Use books.append('Book Title') to add each new book.

4

Mark the end of the allocated memory

Add the string 'END' at the end of the books list to mark the end of allocated memory using the append() method.

Compiler Design

books = ['1984', 'Brave New World', 'Fahrenheit 451']
max_books = 5
books.append('The Handmaid\'s Tale')
books.append('The Road')
# Mark the end of allocated memory
# Your code here

Need a hint?

Use append() again to add the 'END' marker.
