Passing Arrays to Functions in C

When working with C, passing arrays to functions is one of the most common sources of memory bugs and compiler warnings for beginners. Understanding how the language handles arrays under the hood is essential for writing efficient, secure, and modern C programs. This text-based course guides you through the core mechanics of memory allocation, pointer arithmetic, and function parameters. You will transition from writing basic scripts to designing robust C functions that safely process both one-dimensional and two-dimensional arrays. By understanding how data is structured in memory, you will write cleaner code and avoid common pitfalls like buffer overflows and segmentation faults. What you will learn: - Understand how arrays decay into pointers when passed as function arguments - Track array sizes safely by passing length parameters to your functions - Pass and manipulate both one-dimensional and multi-dimensional arrays in C - Apply modern C practices, including const qualifiers, to protect read-only array data - Debug common memory access errors and pointer mismatch warnings - Work with pointer-to-pointer syntax for dynamic array structures The course begins with foundational concepts of computer memory, addresses, and pointer basics before moving on to practical function design and multi-dimensional array manipulation. This logical progression ensures you build a strong mental model of how C manages data in memory. This course is designed for beginner C programmers and computer science students who understand basic loops and variables but want to master pointers and memory management. No prior experience with advanced pointer arithmetic is required. Start reading today to write safer, more efficient C code.
