我的失误是什么？

Question

package main
import "fmt"
func main(){
        a:=[]int{1,2,3,4,5}           //slice of int
        b:=[]struct{                  //another slice of struct
                i int
                j string
        }{
                {1,"精"},
                {2 ,"コバや歌詞"},
                {3,"新一"},
                {4,"武士"},
        }
        c:=[]struct{                           //slice of slices
                d []struct
                e []int
        }{
                {a[:],b[:]},
        }


        fmt.Println(a,b,c)
}

The errors are:-

• ./slices.go:16:3: syntax error: unexpected e, expecting {
• ./slices.go:17:3: syntax error: unexpected {, expecting semicolon or newline or }
• ./slices.go:18:7: syntax error: unexpected ] at end of statement

You are creating c struct wrong. It should contain slice of int for first field and slice of struct of b type as second field.

    c:=[]struct{                           //slice of slices
            d []int
            e []struct{               //another slice of struct
                i int
                j string
            }
    }{
            {a[:],b[:]},
    }

Below code is working

package main
import "fmt"
func main(){
     a:=[]int{1,2,3,4,5}           //slice of int
     b:=[]struct{                  //another slice of struct
                i int
                j string
     }{
             {1,"精"},
             {2 ,"コバや歌詞"},
             {3,"新一"},
             {4,"武士"},
     }
     c:=[]struct{                           //slice of slices
            d []int
            e []struct{               //another slice of struct
                i int
                j string
            }
     }{
            {a[:],b[:]},
     }
     fmt.Println(a,b,c)
}
