# Динамические массивы

## Работа с динамическим массивом

Создадим функцию для считывания целого числа.

```go
func readInt(s string, x * int) {
    fmt.Print(s + ": ")
    var y int = 0
    fmt.Scan(&y)
    *x = y
}
```

Считаем с клавиатуры количество элементов.

```go
var n int = 0
readInt("Input number of elements", &n)
```

Создадим динамический массив.

```go
arr := make([]int, n)
```

Считываем элементы динамического массива.

```go
for i := 0; i < n; i++ {
   var k int = 0
   readInt("Input element", &k)
   arr[i] = k
}
```

Выводим элементы динамического массивы на экран.

```go
fmt.Print("Content of array: ")
for i := 0; i < n; i++ {
   var h int = arr[i]
   fmt.Print(h, "  ")
}
```

## Динамическое увеличение размера массива

Создадим пустой массив.

```go
arr := make([]int, 0)
fmt.Println(arr)
```

Считываем элементы массива.

Ввод оканчивается при введении нуля.

Каждый считанный элемент (кроме нуля) добавляется в конец массива.

```go
for true {
   var x int
   fmt.Scan(&x)
   if x == 0 {
      break
   }
   arr = append(arr, x)
}
```

Выводим сформированный массив на экран.

```go
fmt.Println(arr)
```
