How to capture <return>/<enter> in C

Folks,
I have look at the other threads, and they say to capture the value returned by scanf to see if the user just hit the enter key.
I get nothing back if I just hit enter...
When I enter a single character then enter, I get a returned value of 1.
Here is the code snippet:
printf ("Please give me a single digit number >> "];
Number = getchar ();

while (getchar() != '\n');

here is the oputput from just entering return:


Give me one, single, letter, please >>
|

Note: The cursor drops to the following line, but the program hangs waiting for "something" to read. I need to capture the enter and I'm stumped. Can the wizards help. No, this isn't for an assignment, I'm the professor and I want to demonstrate this, along with other uses of ctype.h. This one is hanging me up.

Seems simple enough.

Code:

---

#include <stdio.h>
int main(void)
{
    int ch, number;
    printf ("Please give me a single digit number >> ");
    number = getchar ();
    while ((ch=getchar()) != '\n') {
        printf("Ate '%c' for breakfast\n",ch);
    }
    printf("You typed a '%c'\n", number);
}


$ gcc foo.c
$ ./a.out
Please give me a single digit number >> 3a
Ate 'a' for breakfast
You typed a '3'

Found the problem, hidden getchar(). Sorry
