◇Common Pitfalls

Skipping the fundamentals — understanding what an array is, its characteristics, and memory layout is essential before tackling operations or pointer relationships
Confusing static allocation with dynamic allocation — int arr[5] is stack-allocated (fixed size), while malloc(5 * sizeof(int)) is heap-allocated (resizable with realloc)
Overlooking that arrays are zero-indexed in C — valid indices for arr[n] are 0 to n-1

◇Summary

TL;DR — This introduction covers the three foundational sub-topics: What is an Array (definition and purpose), Characteristics & Attributes (name, element type, size, dimension), and Memory Allocation (contiguous, static vs. dynamic).
