Thank you for your help,but I still haven't solved my problem.
I reinstalled DMD 2.111.0 today,it's the newest relaese version. 
However,the compiler still keep silent when compiling `dmd 
hello.c`...(If it can't compile,at last it should complain,all 
right? But it did nothing...)
But if I speak `dmd --version` it will tell me:
`DMD64 D Compiler v2.111.0
Copyright (C) 1999-2025 by The D Language Foundation, All Rights 
Reserved written by Walter Bright`

And it can compile a normal D file which doesn't import a C file. 
If the D file imports a C file,the compiler will still keep 
silent...

Oh no that's too bad. I wonder if there may be anything wrong 
with my computer...
