What is the difference between pointers and arrays in C?

What is the difference between pointers and arrays in C?

Pointers are variables that store memory addresses, while arrays are collections of elements stored in contiguous memory.

Can you give me an example of how to use pointers and arrays?

Sure! For an array, you might declare it like this: int arr[5];. For a pointer, you would do: int *ptr; and then assign it to the array's address: ptr = arr;.

Are pointers more efficient than arrays?

Pointers can be more efficient in certain situations, especially when dealing with dynamic memory allocation or when passing large data structures to functions.

What are some common mistakes when using pointers?

Common mistakes include dereferencing null pointers, forgetting to allocate memory, and memory leaks when not freeing allocated memory.
