Pointers and Arrays: Memory Management in C

This lecture covers the relationship between pointers and arrays in the C programming language. It begins by explaining how pointers can be allocated to point to multiple doubles in memory. The instructor illustrates how to access elements in a dynamically allocated array using pointer arithmetic, emphasizing that a pointer can be treated similarly to an array. The lecture also discusses the differences between arrays and pointers, particularly in terms of memory allocation and access. The instructor highlights that arrays are essentially constant pointers to statically allocated memory, while pointers can be dynamically allocated and manipulated. Various examples are provided to demonstrate pointer arithmetic and the implications of using pointers in function arguments. The lecture concludes with a discussion on the memory layout of arrays and pointers, clarifying the distinctions between single and double pointers, and the importance of understanding memory allocation in programming. Overall, this lecture provides a comprehensive overview of pointers and arrays, essential concepts for effective programming in C.
