Are you allowed to use getchar() twice? (seems like a silly question?
read on!)
----------------------------------------------------
kangaroo% cat test.c
#include <stdio.h>
main()
{
int c;
c=getchar(); putchar(c);
c=getchar(); putchar(c);
putchar('\n');
}
kangaroo% gcc test.c
kangaroo% echo "Hi" | a.out
H^@
kangaroo% cc test.c
kangaroo% echo "Hi" | a.out
Hi
----------------------------------
Anybody know what's going on?
