Under turbo cshell, I get the output:
Hello world
Hello Exit 1
leading me to guess that the problem is that
your output buffer isn't getting flushed the
way you might expect it to be. You can fix
that like so:
#include <stdio.h>
void main()
{
printf("Hello ");
fflush(stdout);
if (fork() == 0)
printf("world\n");
}
