Answer 1

It might be useful to assign a null in a string rather than explicitly making some index the null char '\0'. I've used this for testing functions that handle strings ensuring they stay within their appropriate bounds.

With:

char test_src[] = "fuu\0foo";

This creates an array of size 8 with values:

{'f', 'u', 'u', '\0', 'f', 'o', 'o', '\0'}
