A Tour of Go Slicing slices

---恢复内容开始---

Slices can be re-sliced, creating a new slice value that points to the same array.

The expression

s[lo:hi]

evaluates to a slice of the elements from lo through hi-1, inclusive. Thus

s[lo:lo]

is empty and

s[lo:lo+1]

has one element.

package main 

import "fmt"

func main() {
    p := []int{2, 3, 5, 7, 11, 13}
    fmt.Println("p ==", p)
    fmt.Println("p[1:4] ==", p[1:4])

    //missing low index implies 0
    fmt.Println("p[:3] ==", p[:3])

    // missing high index implies len(s)
    fmt.Println("p[4:] ==", p[4:])
}

package main 

import "fmt"

func main() {
    p := []int{2, 3, 5, 7, 11, 13}
    fmt.Println("p ==", p)
    fmt.Println("p[1:4] ==", p[1:4])

    //missing low index implies 0
    fmt.Println("p[:3] ==", p[:3])

    // missing high index implies len(s)
    fmt.Println("p[4:] ==", p[4:])
    var a [2]string
    a[0] = "Hello"
    a[1] = "World"
    fmt.Println(a[0:1])
}
