golang中数组与切片的区别

a := [...]int{1,2,3}   
a := [3]int{1,2,3}

a:= []int{1,2,3}  
a := make([]int, 5) 
a := make([]int, 5, 10)

numbers2 := [...]int{1, 2, 3, 4, 5, 6}
maxIndex2 := len(numbers2) - 1
for i, e := range numbers2 {
   if i == maxIndex2 {
      numbers2[0] += e
   } else {
      numbers2[i+1] += e
   }
}
fmt.Println(numbers2)

numbers3 := []int{1, 2, 3, 4, 5, 6}
maxIndex3 := len(numbers3) - 1
for i, e := range numbers3 {
   if i == maxIndex3 {
      numbers3[0] += e
   } else {
      numbers3[i+1] += e
   }
}
fmt.Println(numbers3)

[7 3 5 7 9 11]
[22 3 6 10 15 21]
