The first time you run it, it sees a number and scans it.
The second time you run it, it hits whitespace of some sort -- a space or newline. This is not a digit, so it gives up.
The third time you run it, it hits the same whitespace. It's going to just keep slamming its head into the wall over and over again.
In summary, don't use scanf, it's a royal pain. Read lines yourself, tokenize them yourself, then use sscanf if you must. It will never pull this trick on you.

wcstok
WCSTOK(3) BSD Library Functions Manual WCSTOK(3)NAME
wcstok -- split wide-character string into tokens
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
wchar_t *
wcstok(wchar_t * restrict str, const wchar_t * restrict sep, wchar_t ** restrict last);
DESCRIPTION
The wcstok() function is used to isolate sequential tokens in a null-terminated wide character string, str. These tokens are separated in
the string by at least one of the characters in sep. The first time that wcstok() is called, str should be specified; subsequent calls,
wishing to obtain further tokens from the same string, should pass a null pointer instead. The separator string, sep, must be supplied each
time, and may change between calls. The context pointer last must be provided on each call.
The wcstok() function is the wide character counterpart of the strtok_r() function.
RETURN VALUES
The wcstok() function returns a pointer to the beginning of each subsequent token in the string, after replacing the token itself with a null
wide character (L'
