What is pointer arithmetic in C?

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

Can you give me an example of how it works?

Sure! If you have an integer array and a pointer pointing to its first element, incrementing the pointer moves it to the next integer.

What happens if I go beyond the array bounds?

Accessing memory beyond the array bounds leads to undefined behavior, which can cause crashes or incorrect results.

How can I safely use pointer arithmetic?

Always ensure your pointer stays within the allocated memory range and use bounds checking to prevent errors.
