Kuidas suurendada funktsioonile edastatava lõigu suurust programmeerimiskeeles?

In Go, a slice is a structure that contains a pointer to an array, a length, and a capacity. If you want to increase the size of a slice passed to a function, you can do the following:

• Pass the slice by value, but create a new slice inside the function with increased length or capacity using the append function.
• If you need to modify the slice itself (for example, increase its length) and have the changes visible outside, you can pass a pointer to the slice (*[]T), then inside the function you can reassign the slice.

Example of increasing a slice inside a function with returning a new slice:

func extendSlice(s []int, n int) []int {
    // Add n zero elements
    s = append(s, make([]int, n)...) 
    return s
}

func main() {
    s := []int{1, 2, 3}
    s = extendSlice(s, 2)
    fmt.Println(s) // [1 2 3 0 0]
}

If the function should modify the slice without returning it, you can use a pointer:

func extendSlicePtr(s *[]int, n int) {
    *s = append(*s, make([]int, n)...) 
}

func main() {
    s := []int{1, 2, 3}
    extendSlicePtr(&s, 2)
    fmt.Println(s) // [1 2 3 0 0]
}

Thus, to increase the size of a slice inside a function, you need to either return a new slice or pass a pointer to the slice.
