Module 5: Arrays and Strings

Overview

This module explores arrays and strings in C, fundamental data structures for storing and manipulating collections of data. You’ll learn about array declaration, initialization, and access, as well as multi-dimensional arrays and advanced array concepts. The module also covers string handling in C, including string literals, character arrays, and the standard library functions for string manipulation.

Learning Objectives

By the end of this module, you will be able to: - Declare, initialize, and access arrays of various types - Work with multi-dimensional arrays and jagged arrays - Understand array bounds and buffer overflow prevention - Manipulate strings using character arrays and standard library functions - Implement string searching, comparison, and manipulation algorithms - Apply arrays and strings to solve practical programming problems - Understand the relationship between arrays and pointers - Use variable-length arrays (C99 feature) appropriately

Chapters

  1. Arrays - Declaration, initialization, access, and basic operations
  2. Strings - Character arrays, string literals, and string manipulation
