告诉我这段代码GOLANG有什么问题

package main

import (
    "fmt"
    "math"
)

func main() {

    distencecalc()
}

func distencecalc() {

    fmt.Println("X1 :")
    var x1 float64
    fmt.Scanf("%f", &x1)
    fmt.Print("")
    fmt.Println("Y1 :")
    var y1 float64
    fmt.Scanf("%f", &y1)
    fmt.Print("")
    fmt.Println("Z1 :")
    var z1 float64
    fmt.Scanf("%f", &z1)
    fmt.Print("")
    fmt.Println("X2 :")
    var x2 float64
    fmt.Scanf("%f", &x2)
    fmt.Print("")
    fmt.Println("Y2 :")
    var y2 float64
    fmt.Scanf("%f", &y2)
    fmt.Print("")

    fmt.Println("Z2 :")
    var z2 float64
    fmt.Scanf("%f", &z2)
    fmt.Print("")

    var Xcalc = x2 - x1
    var Ycalc = y2 - y1
    var Zcalc = z2 - z1



    var calcX = math.Pow(Xcalc, 2)
    var calcY = math.Pow(Ycalc, 2)
    var calcZ = math.Pow(Zcalc, 2)


    var allcalc = calcX + calcZ + calcY
    fmt.Println("the result is :")
    fmt.Println(math.Sqrt(allcalc))
}

问题是我先编译然后运行它询问x1的程序，然后输入值并询问y1和z1。
