[Ilugc] C pgm - Recursive -segmentation fault

As people rightly pointed out it must be stack overflow.
But tell me an recursive function shld run forever(atleast in theory) right
???
Consider a case where my program does something repeatedly ..in such a case
I write a recursive program .what's the point in writing a recursive
function if it is going to exit abruptly.
Now the question arises how to clear this stack etc etc ????

What is the problem here?
For any recursive function, you should have an exit criteria. Otherwise it
would recurse forever. Your function doesn't have an exit point.
When I run this program, Recursive Function R(), Called only 523714
times, after that segmentation fault occurs WHY?
Since you don't have an exit point, repeated call of the function by itself
leads to stack overflow.
HTH.
