Quizplus · Accepted Answer

The code defines and initializes an integer variable `x` with the value 2. Then the `getValue()` function is called with `x` as the argument. Inside the `getValue()` function, `num` is a local variable that is initialized with the value of `x`, which is 2. Then `num + 5` is returned, which is 7. So, the statement `cout << getValue(x) << endl;` will display the value 7 on the screen. Therefore, the correct answer is C.
