I didn't program in C for a long time but as far as I remember,
scanf read 1 string using white space as separator.

to enter aaa bbb ccc
you need scanf("%s %s %s", ...) or gets

use gets
or scanf("%s", ..)
followed by
while('\n'!=getchar());
but you loose the extra typed words

hope this helps.

The reverse is true for the example below: ie you were encountering
problems before, but not realising it.

You can't flush(stdin). Nothing wrong with Cygwin here, simply the other
compilers implementing stuff that isn't part of the language. The FAQ
for comp.lang.c or alt.comp.lang.learn.c-c++ will no doubt give you
ample insight.
