数组初始化，数组的地址，把值放入数组的地址中，&符号使用

var numArr01 [3]int = [3]int{1,2,3}
    fmt.Println("numArr01=", numArr01)

    var numArr02 = [3]int{5,6,7}
    fmt.Println("numArr02=", numArr02)

    var numArr03 = [...]int{8,9,10}
    fmt.Println("numArr03=", numArr03)

    var numArr04 = [...]int{1:800, 0:900, 2:999}
    fmt.Println("numArr04=", numArr04)

    strArr05 := [...]string{1:"tom", 0:"jack", 2:"malina"}
    fmt.Println("strArr05=", strArr05)

var numArr01 [3]int = [3]int{1,2,3}
    fmt.Println("numArr01=", numArr01)

    var numArr02 = [3]int{5,6,7}
    fmt.Println("numArr02=", numArr02)
