C Programming: Memory Representation of Char Arrays

To write secure and efficient C programs, you must understand exactly how data lives in memory. Character arrays and strings are among the most common sources of bugs and security vulnerabilities for developers who do not grasp their low-level mechanics. This text-only course demystifies memory allocation, showing you exactly how bytes are structured behind the scenes. You will transition from writing guesswork code to confidently managing memory, calculating boundaries, and handling string data with precision. What you'll learn: - Understand the foundational structure of char arrays and how they store data in memory - Analyze the critical role of the null terminator in C string handling - Differentiate between sizeof and strlen when calculating memory allocation and string length - Learn modern safe string practices to prevent buffer overflows and security risks - Practice reading memory layouts and tracing pointer-based string operations Starting with basic definitions and memory concepts, this course guides you through step-by-step written explanations and practical code analysis. You will explore memory visualization diagrams represented in text, compare standard library functions, and learn to write robust code that respects system boundaries. This course is designed for beginner C programmers and computer science students who want to master low-level memory concepts. No prior memory-management experience is required.
