Question
**Problem: What is the final value of y?** ```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. The program initializes two integer variables: `x` with a value of 4 and `y` with a value of 6. 2. The first `if` statement checks whether `x` is less than 10. Since `x` is 4, the condition is true, and the code inside this `if` block will execute. 3. Inside the first `if` block, there is another `if` statement that checks if `y` is less than 5. - Since `y` is 6, this condition is false, so the `else` block executes. 4. In the `else` block, `y` is set to 7. 5. The outer `else` block will not execute because the condition `x < 10` was true. Thus, the final value of `y` is 7.
