### Variable Initialization in C++

**Question 3**  
How may the int variables `months`, `days`, and `years` be defined in one statement, with `months` initialized to 12 and `years` initialized to 15?

**Answer:**  
The int variables can be defined and initialized in a single statement in C++ as follows:

```cpp
int months = 12, days, years = 15;
```

**Explanation:**

- This statement declares three integer variables: `months`, `days`, and `years`.
- The variable `months` is initialized to 12.
- The variable `years` is initialized to 15.
- The variable `days` is declared but not initialized.
