The scanf (" % d, & amp; N "); Instead the scanf (" % d ", & amp; N);
The scanf (" % d ", b); Instead the scanf (" % d ", & amp; b);

The inside of the printf % and variable of one to one correspondence relation
The scanf % and variables and the variables inside before add don't add & amp; One-to-one correspondence relationship
Is the place that C code is very easy to get wrong, and generally don't compile error,
So during the compilation of source code is worth specially carefully check it again and even many times before,
