Module: Introduction to Data Structures

Lesson 1: Understanding Arrays

Arrays are fundamental data structures that store a fixed-size sequential collection of elements of the same type. This lesson covers their basic definition, memory allocation, and common operations like initialization, accessing elements, and basic traversal.

Key Concepts

Definition of an array and its contiguous memory allocation.
Indexing: zero-based vs. one-based.
Common operations: declaration, initialization, element access, and update.
Distinction between static and dynamic arrays.

Code Example: Array Initialization (Python)

            
# Declaring and initializing an array
my_array = [10, 20, 30, 40, 50]

# Accessing an element
print(f"First element: {my_array[0]}") # Output: 10

# Iterating through an array
for element in my_array:
    print(element)
