To all you C guru's out there HELP!

I must be missing something totally obvious but the code below
is not working as expected. :-(  scanf is supposed to return the 
number of successful conversions correct? In the code below
whether I type in a number or a string of characters, test always equals
one. 

Shouldn't test become zero when a non numeric input is typed in?

This happens in think C 4.0.2

while ((test=scanf("%d",&thenumber))!=EOF)
 {
  printf("The Number %d  Test %d \n",thenumber,test);
  printf("Enter a number ");
  thenumber=0;
  fflush(stdin);
 }

Also when I compiled this on my unix machine after I typed in a string
of characters it went into an endless loop not allowing me to enter in 
another value. It just kept printing "The Number ..."

What the heck am I doing wrong.

Thanks

Matt
