What is pointer arithmetic in C++?

What is pointer arithmetic in C++?

Pointer arithmetic allows you to perform operations on pointers, like addition and subtraction, to navigate through arrays.

Can you give me an example of how to use pointer arithmetic?

Sure! If you have an array int arr[5] = {1, 2, 3, 4, 5};, you can access the second element using *(arr + 1).

What happens if I go out of bounds with pointer arithmetic?

Going out of bounds can lead to undefined behavior, which may cause your program to crash or produce incorrect results.

Are there any best practices for using pointer arithmetic?

Yes, always ensure that your pointers point to valid memory locations and avoid arithmetic that goes beyond allocated memory.
