我一直在用 Go 嘗試一些東西，但遇到了一個(gè)我無法弄清楚的問題。package mainimport "fmt"import "strconv"func writeHello(i int, ) {        fmt.Printf("hello, world "+strconv.Itoa(i)+"\n")}type SliceStruct struct {    data [][]int;}func (s SliceStruct) New() {    s.data=make([][]int,10);}func (s SliceStruct) AllocateSlice(i int) {    s.data[i]=make([]int,10);}func (s SliceStruct) setData(i int, j int, data int) {    s.data[i][j] = data;}func (s SliceStruct) getData(i int, j int) int {    return s.data[i][j]}func useSliceStruct(){    sliceStruct := SliceStruct{};    sliceStruct.New();    for i := 0; i < 10; i++ {        sliceStruct.AllocateSlice(i);        for j:=0; j<10; j++ {             sliceStruct.setData(i,j,i);            writeHello(sliceStruct.getData(i,j));        }    }}func dontUseSliceStruct(){    data:=make([][]int,10);    for i := 0; i < 10; i++ {        data[i]=make([]int,10);        for j:=0; j<10; j++ {            data[i][j] = i;            writeHello(data[i][j]);        }    }}func main() {    dontUseSliceStruct();    useSliceStruct();}當(dāng)它到達(dá)函數(shù) useSliceStruct 時(shí)，代碼在第一次調(diào)用 AllocateSlice() 時(shí)失敗，并出現(xiàn)索引超出范圍錯(cuò)誤。據(jù)我所知，這兩種方法的代碼做了相同的事情。那么我錯(cuò)過了什么？
