Question

Transcribed Image Text: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.
