How can I avoid pointer arithmetic errors in C?

What are pointer arithmetic errors in C?

Pointer arithmetic errors occur when you incorrectly calculate the address of an element in an array, leading to accessing invalid memory.

How can I prevent these errors when coding?

To prevent pointer arithmetic errors, always ensure that your pointer calculations stay within the bounds of the array and use proper data types.

Can you give me an example of a common mistake?

Sure! A common mistake is incrementing a pointer beyond the array's end, like this: ptr + size where ptr points to the first element.

What tools can help me detect these errors?

You can use tools like Valgrind or AddressSanitizer to detect memory access errors, including pointer arithmetic mistakes.
