When reading input using scanf, the input is read after the return key is pressed but the newline generated by the return key is not consumed by scanf, which means the next time you read a char from standard input there will be a newline ready to be read.

Why is the second scanf() not working?

Why does scanf() leave a newline in the input buffer?

It is coming out of compiler. It’s because the previous scanf () left a newline in the input buffer. A simple fix to tell scanf to ignore all the whitespaces: Any whitespace directive ( space, etc) in the format string tells scanf ignore any number of whitespaces in the input.

Does getchar() skip the second scanf()?

It doesn’t skip the second scanf (); the second scanf () reads the newline left behind by the first scanf (). Most format codes skip white space; the \%c format does not skip white space. calling getchar () before scanf will also purge the stored line break.
