An In-Depth Understanding of Memory and Pointers in C Course Syllabus

Overview: This course provides a comprehensive, hands-on journey into C's memory model and pointer mechanics, designed for developers seeking mastery in low-level programming. Over eight modules, learners progress from foundational concepts to advanced memory management techniques, including custom allocator design. Each module blends theory with practical coding exercises, debugging sessions, and real-world applications. With a recommended commitment of approximately 60-70 hours total, this course is structured to build deep, applicable expertise in memory safety, pointer manipulation, and efficient C programming practices.

Module 1: C Memory Model Essentials

Estimated time: 10 hours

• Variable storage durations: automatic vs. static
• Memory regions: stack, heap, and static segments
• Stack frame layout and function call mechanics
• Using objdump to inspect memory layout

Module 2: Pointer Fundamentals

Estimated time: 10 hours

• Pointer syntax and declaration
• Indirection (* operator) and address-of (& operator)
• NULL and void pointers
• Implementing swap and array traversal using pointers

Module 3: Pointer Arithmetic & Arrays

Estimated time: 10 hours

• Pointer arithmetic: incrementing and decrementing
• Pointer–array equivalence
• Multi-dimensional arrays and memory layout
• Implementing matrix operations using pointer arithmetic

Module 4: Dynamic Memory Management

Estimated time: 10 hours

• Using malloc and calloc for dynamic allocation
• Resizing memory blocks with realloc
• Proper use of free to avoid memory leaks
• Building a dynamic vector with growth capability

Module 5: Function Pointers & Callbacks

Estimated time: 10 hours

• Declaring and calling function pointers
• Implementing callback patterns
• Creating dispatch tables
• Building a generic sort with comparison callbacks

Module 6: Pointers-to-Pointers & Data Structures

Estimated time: 10 hours

• Understanding double pointers (pointer-to-pointer)
• Dynamic 2D arrays using pointer arrays
• Implementing linked lists with pointers
• Tree structures using dynamic node allocation

Module 7: Memory Safety & Debugging

Estimated time: 10 hours

• Common memory pitfalls: use-after-free, buffer overflows
• Memory alignment issues
• Using valgrind for memory leak detection
• Diagnosing and fixing bugs with AddressSanitizer

Module 8: Best Practices & Capstone Project

Estimated time: 15 hours

• Memory alignment and performance considerations
• Designing a custom memory-pool allocator
• Integrating RAII-like patterns using macros
• Documenting and testing the allocator in a sample application

Prerequisites

• Familiarity with basic C syntax and control structures
• Understanding of functions, loops, and data types in C
• Basic experience compiling and running C programs

What You'll Be Able to Do After

• Explain the differences between stack, heap, and static memory segments
• Declare, manipulate, and debug pointers confidently
• Allocate and manage dynamic memory safely using C standard functions
