The answer is C, an expression that evaluates to true or false.
In computer science, a Boolean expression is an expression used in programming languages that produces a Boolean value when evaluated. A Boolean value is either true or false.

Answer:
Constructor issue
Explanation:
When you look at the Class A, the constructor takes one argument as a parameter, a String.
A(String newS) {
s = newS;
}
However, in the main, the constructor does not take any argument as a parameter.
A a = new A();
That's why the code does not compile.
Answer:
Option 1: May crash at runtime because it can input more elements than the array can hold
Explanation:
Given the code as follows:
- int[] a = {1, 3, 7, 0, 0, 0};
- int size = 3, capacity = 6;
- int value = cin.nextInt();
- while (value > 0)
- {
- a[size] = value;
- size++;
- value = cin.nextInt();
- }
From the code above, we know the <em>a</em> is an array with six elements (Line 1). Since the array has been initialized with six elements, the capacity of the array cannot be altered in later stage.
However, a while loop is created to keep prompting for user input an integer and overwrite the value in the array started from index 3 (Line 4- 9). In every round of loop, the index is incremented by 1 (Line 7). If the user input for variable <em>value</em> is always above zero, the while loop will persist. This may reach a point where the index value is out of bound and crash the program. Please note the maximum index value for the array is supposedly be 5.
Answer:
Destroying all identifiers connected to the data.
Explanation:
Identifiers are your virtual location when navigating, if you destroy your 'Virtual ID', nobody could identify you. Also, you could hide your identifiers, in this case, there's a small risk.
