Foundations of Memory Safety and Program Structure

Writing reliable software requires a deep understanding of how computers store and manage data. Without proper guardrails, common errors like memory leaks, buffer overflows, and dangling pointers can compromise security and crash your applications. This text-based course guides you through the core principles of memory safety and clean program architecture. You will transition from writing unpredictable code to structuring robust, secure, and highly efficient programs using modern safety paradigms. What you'll learn: Understand foundational memory concepts, including stack and heap allocation; Identify common memory vulnerabilities such as buffer overflows and use-after-free errors; Apply modern memory management strategies, including ownership models and smart pointers; Structure programs logically using modular design principles to enhance maintainability; Explore static analysis tools that help enforce memory safety automatically. You will start with essential definitions of hardware memory before moving on to practical architectural patterns and modern safety techniques. Through clear written explanations and structured code analysis, you will build a solid mental model of how safe programs execute. This course is designed for aspiring systems programmers and software developers who want to write safer code. No prior experience with low-level memory management is required.
