```go
import "c"

c.printf C"Hello, llgo!\n"
c.fprintf c.Stderr, C"Hi, %6.1f\n", 3.14
c.printf c"Hello, llgo!\n"
c.fprintf c.Stderr, c"Hi, %6.1f\n", 3.14
```

Here `import "c"` is used to import libc. In this example we call two C standard functions `printf` and `fprintf`, passing a C variable `stderr` and two C strings in the form of `C"xxx"` (a Go+ syntax to represent C-style strings).

To run this demo, you need to set the `GOP_GOCMD` environment variable first.

Here we use `import "c"` to import libc. It's an abbreviation for `import "github.com/goplus/llgo/c"`. It is equivalent to the following code:

```go
import "github.com/goplus/llgo/c"

c.printf C"Hello, llgo!\n"
c.fprintf c.Stderr, C"Hi, %7.1f\n", 3.14
