Please add the following to the program

1. Display the smallest and largest values in each of the arrays. This should be displayed AFTER displaying the sorted numbers in the array.

2. Write and use a function that will calculate the average of the numbers in an array of doubles. This function should be called for each of the arrays of doubles and the return value should be displayed in main() AFTER displaying the sorted numbers in the array.

double average( double array[], int numberOfValues )

This function will calculate the average of the values in an array of doubles.

This function takes two arguments: the first argument is an array of doubles that holds the numbers to be used in the calculation, and the second argument is an integer that holds the number of values to use in the calculation. The function returns a double: the average of the values in the array of doubles.

3. Write and use a function that will calculate the standard deviation of the numbers in an array of doubles. This function should be called for each of the arrays of doubles and the return value should be displayed in main() AFTER displaying the sorted numbers in the array.

double standardDeviation( double array[], int numberOfValues )

This function will calculate the standard deviation of the values in an array of doubles.

This function takes two arguments: the first argument is an array of doubles that holds the numbers to be used in the calculation, and the second argument is an integer that holds the number of values to use in the calculation. The function returns a double: the standard deviation of the values in the array of doubles.

The standard deviation is calculated as follows:

where

?( x² ) is the sum of the numbers squared

(? x)² is the square of the sum of the numbers

n is the number of values

The following is the extra output for the runs of the program from earlier in the assignment write-up.

Run 1 using srand(0)

First Array: Smallest Value: 1.286 Largest Value: 147.794 Average: 71.140 Standard Deviation: 45.737 Second Array: Smallest Value: 0.545 Largest Value: 149.149 Average: 73.449 Standard Deviation: 43.368 

Run 2 using srand(time(0))

First Array: Smallest Value: 0.989 Largest Value: 148.563 Average: 76.127 Standard Deviation: 42.802 Second Array: Smallest Value: 3.745 Largest Value: 149.368 Average: 68.219 Standard Deviation: 47.113

(??) 2 ? x2) Standard deviation ? 1
