go中的数组和切片

声明:

package main

import "fmt"

func main() {
	// 数组声明
	s1 := make([]int,5)
	fmt.Printf("The length of s1: %d\n", len(s1))   //5
	fmt.Printf("The capacity of s1: %d\n", cap(s1))   //5
	fmt.Printf("The value of s1: %d\n", s1)    // [0 0 0 0 0]

	s4 := [5]int{0,1,2}
	fmt.Printf("The length of s4: %d\n", len(s4))   //5
	fmt.Printf("The capacity of s4: %d\n", cap(s4))   //5
	fmt.Printf("The value of s4: %d\n", s4)   // [0 1 2 0 0]

	// 切片声明
	s2 := make([]int, 5, 8)
	fmt.Printf("The length of s2: %d\n", len(s2))   //5
	fmt.Printf("The capacity of s2: %d\n", cap(s2))   //8
	fmt.Printf("The value of s2: %d\n", s2)   // [0 0 0 0 0]

	s3 := []int{0,1,2,3,4}
	fmt.Printf("The length of s3: %d\n", len(s3))   //5
	fmt.Printf("The capacity of s3: %d\n", cap(s3))   //5
	fmt.Printf("The value of s3: %d\n", s3)   // [0 1 2 3 4]
