Question
**Problem: Understanding Post-Increment in Programming**

```plaintext
x = 9;
y = x++;
```

**Question**: What are the values of `x` and `y` after the two statements execute?

---

**Explanation**: 

In the given code, `x` is initially assigned a value of `9`. The line `y = x++` uses the post-increment operator, which means the value of `x` is used for the assignment to `y` before `x` is incremented.

- **Initial Values**:
  - `x = 9`
  - The value `9` is assigned to `y`.

- The post-increment operator (`x++`) then increases the value of `x` by `1`.

- **Final Values**:
  - `x = 10`
  - `y = 9`

---

**Answer**:

- x = [10]
- y = [9]
