尽管在 Golang 中数组具有固定的大小,但您可以利用append通过创建新切片来克服这个限制。让我们揭示如何在数组中实现动态扩展。 package main import "fmt" func main() { array := [3]int{1, 2, 3} slice := append(array[:], 4, 5) fmt.Println("Updated slice:", slice) // Output: Updated slic...

// The append built-in function appends elements to the end of a slice. If // it has sufficient capacity, the destination is resliced to accommodate the // new elements. If it does not, a new underlying array will be allocated.
