## Answer 1, Authority 100%

Because `B `

– `int `

and 4 too `int `

Row `Double C = b / 4; `

works like this:

```
double c = (double) (b / 4);
```

first occurs integer division, and then bringing to `double `

;

To the division was not integer Write:

```
double c = b / 4.0;
```

In this case, `b `

will be `Double `

everything will be correct.
