Question
The image shows a coding problem with the question: "What is the final value of y?"

Here is the code snippet provided:

```cpp
int x = 4;
int y = 6;
if (x < 10) {
    if (y < 5) {
        y = y + 1;
    }
    else {
        y = 7;
    }
}
else {
    y = y + 10;
}
```

Explanation:

1. **Variable Initialization**:
   - `x` is set to 4.
   - `y` is set to 6.

2. **First Conditional Statement**: `if (x < 10)`
   - Since `x` is 4, which is less than 10, the code inside this block executes.

3. **Nested Conditional Statement**: `if (y < 5)`
   - The condition checks if `y` is less than 5.
   - Since `y` is 6, which is not less than 5, this block is skipped, and the `else` block is executed.

4. **Else Block within First Conditional**:
   - `y` is set to 7.

5. **Outer Else Block**:
   - This block is part of the first conditional `else`, but since `x < 10`, this part is skipped.

After executing the code, the final value of `y` is 7.
