------------code-----------
import stream;
void main()
{
  char something;

  // with scanf()
  stdout.printf("Type a character: ");
  stdin.scanf("%c",&something);
  stdout.printf("You typed: %c\n", something);
  stdout.printf("Now type something else: \n");
  stdin.scanf("%c",&something);
  stdout.printf("You typed: %c\n\n", something);

  // with getc()
  stdout.printf("Type a character: ");
  something = stdin.getc();
  stdout.printf("You typed: %c\n", something);
  stdout.printf("Now type something else: \n");
  something = stdin.getc();
  stdout.printf("You Typed: %c", something);
}

------------output-----------
C:\d>scan
Type a character: 2
You typed: 2
Now type something else:
You typed:

Type a character: You typed:

Now type something else:
+
You Typed: +

I think it would be helpful if you would make clear what you desired.

Sorry!

I'm simply attempting to get two characters from the user with successive
calls to either scanf() or getc(). When first prompted, if the user inputs
multiple characters into the stream, the scanf() or getc() will read from
the remaining characters. However, if the user only inputs one character and
then press enter, both scanf() and getc() ignores the next two calls.  Only
on the third call will the user get a chance to input additional
information.

It would probably be enlightening for you if you print out the ascii code of
each character received instead of the characters themselves.

The question then, should be: How do I flush the buffer after extracting the
first character? The closest thing I can find is fflush(), which does not
work on stdin.

I think, like in C, you have to take the newline out of the stream first or
it'll be the next input. So, perhaps you want to loop getc until it's \n,
printing out only the first one. In C it could return EOF, but in D it could
throw a ReadError.

IC...
I'll try it out sometime tomorrow evening after I finish my homework!
