Time for a winter dev challenge! In C, when you have an array and take its address, something interesting happens with sizeof. The array itself and a pointer to the array are fundamentally different types, and this code demonstrates exactly why that matters. Can you explain what's happening here? This is a subtle but important distinction in C programming that affects how you pass arrays to functions and understand memory layout. Share your explanation in the comments!
