Will run infinitely, but STACK-OVERFLOW will occur as the main () is being called continuously and control is not going back to the calling function.

In this question, main() is called recursively & for each call of main() the memory is allocated in stack & when the stack gets full the pointer which allocates memory will reach in another segment & it will give Segmentation fault (core dumped).
