How to Catch Errors in Embedded Development at Compile Time?

Have you ever thought about how some simple syntax rules in C can lead to clever methods? For example, the length of an array in C cannot be negative; of course, it makes no sense for an array length to be negative. For instance, int arr[1]; is correct, while int arr[-1]; is incorrect. This rule … Read more
