Is there any hard-wired limit on recursion depth in C

Question

The program under discussion attempts to compute sum-of-first-n-natural-numbers using recursion. I know this can be done using a simple formula n

Answer 1

The C standard does not define the minimum supported depth for function calls. If it did, which is quite hard to guarantee anyway, it would have it mentioned somewhere in section 5.2.4 Environmental limits.
