Question

Which statements below are true ? (multiple answers)

```Go
func main() {
    var count int
	var wg sync.WaitGroup

for range 1000 {
		wg.Add(1)
		wg.Go(func() {
			defer wg.Done()
			count++
		})
	}

wg.Wait()
	fmt.Println(count)
}
```

Accepted Answer

Data race detected. The result might be inferior to a  1000

Accepted Answer

Replacing `count`  by an `atomic.Int64` then calling `count.Add(1)` corrects the problem

Accepted Answer

Running `go run -race` or `go test -race` will detect the issue

Answer

`wg.Wait()` ensures a secure access to `count`

Answer

The result will always be 1000
