Consider the partially-filled array named a. what does the following loop do? (cin is a scanner object)

int[] a = {1, 3, 7, 0, 0, 0};
int size = 3, capacity = 6;

int value = cin. nextint();
while (size < capacity & & value > 0)
{
a[size] = value;
size++;
value = cin. nextint();
}

1. reads one value and places it in the remaining first unused space endlessly.
2. crashes at runtime because it tries to write beyond the array.
3. reads up to 3 values and places them in the array in the unused space.
4. reads up to 3 values and inserts them in the array in the correct position.

3. Reads up to 3 values and places them in the array in the unused space.

Explanation:

cin.NextInt() reads the next value from the Scanner.

The while is just while the size is lesser than the capacity and the value is positive. It may read up to 3 values, and puts at the position size; Size starts at 3, that is, the first index which the value is 0, and goes up to 5. So it is the unused positions.

The correct answer is:

3. Reads up to 3 values and places them in the array in the unused space.

well you could find somebody who doesn't want theirs and ask for it or possibly trick a dealer into giving it to you for free.
