 __input_arithmetic(basic_istream<_CharT, _Traits>& __is, _Tp& __n) {
-#ifndef _LIBCPP_NO_EXCEPTIONS
-    try
+    ios_base::iostate __state = ios_base::goodbit;
+    typename basic_istream<_CharT, _Traits>::sentry __s(__is);

             default:
-                read(__s, _VSTD::min(__c, __n));
                 break;
