# 使用自定义包中的结构体

下面的例子中，main.go 使用了一个结构体，它来自 struct\_pack 下的包 structPack。

示例 10.5 [structPack.go](https://github.com/yangchuansheng/the-way-to-go_ZH_CN/tree/f30ab7d8c58f85840a0afb548024b93642b518d5/eBook/examples/chapter_10/struct_pack/structPack.go)：

```go
package structPack

type ExpStruct struct {
    Mi1 int
    Mf1 float32
}
```

示例 10.6 [main.go](https://github.com/yangchuansheng/the-way-to-go_ZH_CN/tree/f30ab7d8c58f85840a0afb548024b93642b518d5/eBook/examples/chapter_10/main.go)：

```go
package main
import (
    "fmt"
    "./struct_pack/structPack"
)

func main() {
    struct1 := new(structPack.ExpStruct)
    struct1.Mi1 = 10
    struct1.Mf1 = 16.

    fmt.Printf("Mi1 = %d\n", struct1.Mi1)
    fmt.Printf("Mf1 = %f\n", struct1.Mf1)
}
```

输出：

```
Mi1 = 10
Mf1 = 16.000000
```
