go中array与slice

刚接触go时间不长，关于array与slice做一个笔记

eg:

        package main
        
        import "fmt"
        
        func main() {
            var arr1 [5]int
        
            arr2 := [3]int{1, 3, 5}
            arr3 := [...]int{2, 4, 6, 8, 10}
        
            var grid [4][5]int
        
            fmt.Println(arr1, arr2, arr3)
            fmt.Println(grid)
        
            printArray(arr1)
            printArray(arr3)
        
            fmt.Println(arr1, arr2, arr3)
            fmt.Println(grid)
        }
        func printArray(ints [5]int) {
            ints[0] = 100
            for i, v := range ints {
                fmt.Println(i, v)
            }
        }

eg2:

        package main

        import "fmt"

        func main() {
            var arr1 [5]int

            arr2 := [3]int{1, 3, 5}
            arr3 := [...]int{2, 4, 6, 8, 10}

            var grid [4][5]int

            fmt.Println(arr1, arr2, arr3)
            fmt.Println(grid)

            printArray(arr1[:])
            printArray(arr3[:])

            fmt.Println(arr1, arr2, arr3)
            fmt.Println(grid)
        }
        func printArray(ints []int) {
            ints[0] = 100
            for i, v := range ints {
                fmt.Println(i, v)
            }
        }
