Hi,
I am taking a C class in school this semester, and the instructor gave us the
following example:

#include <stdio.h>          /* Please note:  I used <dos/stdio.h> in the unix
			       environment */
main()
{
	char a, b, c, d, e;
	char whats_left[20];
	int x;

	printf("\nKey in a bunch of characters like 1234...9cr:  ");
	scanf("%c%c%c", &a, &b, &c);
	printf("\nYou typed in >>%c%c%c<<", a, b, c);
	scanf("%c%c", &d, &e);
	printf("\nYou had these left over >>%c%c<<", d, e);
	putc('\n', stdout);
	scanf("%s", whats_left);
	printf("\n>>%s<<", whats_left);
   	printf("\n>>%s<<", &a);
	x = getchar();
	if(x == EOF)
		printf("\nInput stream empty.");
	else;
		printf("\nGot back >>%d%x<<", x, x);
}

I have entered and compiled this on Turbo C 1.5, and it runs like it should.
I enter:  123456789
and the first thing it prints is the >>123<<, then >>45<<, then >>6789<<,
then >>123456789<<, and I get 'Got back >>10a<<'

On the Unix system I enter the same numbers, and I get >>123<< >>45<< >>6789<<
and here's one of the kludges:  >>126789<<, and for 'Got back', it shows
>>00<<..  Why?

Also, when I try to re-direct as follows:
	1) example > output
	   123456789  (<-- what I type in after (1))
	   then I get a core dump, and a message (do not remember exactly,
	   will redo and post)
	2) example < numlist > output  (numlist contains 123456789)    
    	   I get the same core dump as in (1).  Why??
Any help would be appriciated.
    
    
Dave
