// 08_多个变量或常量的定义
package main

import (
    "fmt"
)

func main() 
    //不同类型变量的声明（定义）
    //var a int
    //var b float64
    var (
        a int
        b float64
    )

    a, b = 10, 3.14
    fmt.Println("a = ", a)
    fmt.Println("b = ", b)

    // const i int = 10
    // const j float64=3.14

    const (
        j int     = 10
        i float64 = 3.14
    )

    fmt.Println("i = ", i)
    fmt.Println("j = ", j)
    //可以自动推导类型
    const (
        m = 10
        n = 3.14
    )

    fmt.Println("m = ", m)
    fmt.Println("n = ", n)
