Write the `hasChar()` function that checks whether a string contains a given character (case-sensitive). The function takes two arguments:

* String
* Character to look for

```javascript
hasChar('Hexlet', 'H'); // true
hasChar('Hexlet', 'h'); // false
hasChar('Awesomeness', 'm'); // true
hasChar('Awesomeness', 'd'); // false
```
