I was meaning this as a bug report. But wanted to point out your
solution does not work. I was interested in D back in 1.0 days
but soo much has changed in d 2.0 that I'm reading through the
"Programming in D" book to learn all the new stuff and came
across this odd un-helpful error.
...
readf(" %s", &studentCount);
...
readf(" %s", &teacherCount);
...
that way it will ignore any non int chars left on the stdin
stream.
