1. In the following code the setPreferredSize method sets the size of the text, "Have a good day". ``` label = new Jlabel("Have a good day", SwingConstants.CENTER); label.setPreferredSize(new Dimension(400,200)); ``` 2. When using a slider, by default, tick marks are not displayed, and setting their spacing does not cause them to be displayed. 3.When a JList component is added to a JScrollPane object, a border will automatically appear around the list. 4.You can create a label with an image, or with both an image and text.

Complete the program below by writing functions average and deviation. The program's purpose is to input a list of real numbers, compute their average, and display a table with each number and its deviation from the average. For example, if the data were 4.00, 12.00, 7.00, and 5.00 (average = 7.00), the deviation list would be -3.00, 5.00, 0.00, and -2.00.

#include 
#include 
using namespace std;

double average(                                                       );

void deviation(                                                       );

const int MAX_SIZE = 20;

int main()
{
	double mean;
	double nums[MAX_SIZE];
	double devFromMean[MAX_SIZE];
	int	numsSize;
	
	cout << "Enter the number of elements in the list => ";
	cin >> numsSize;
	cout << "Enter the elements of the list separated by a space => ";
	
	for (int i = 0; i < numsSize; ++i)
		cin >> nums[i];	

	mean = average( nums, numsSize );
	cout << "The mean is " << mean << endl;

	deviation( devFromMean, nums, numsSize, mean );

 	for (int i = 0; i < numsSize; ++i)
		cout << setw( 10 ) << nums[i] << setw( 10 ) << devFromMean[i] 
               << endl;

	return 0;
}


// Returns the average of the first n elements of list
double average(                                                       )










// Fills each of the first n elements of devList with the deviation from 
// givenVal of the corresponding element of list.
