Write a program that will prompt a user to enter three numbers of datatype double in main.

The program will then call a function called calcAverage that includes all three numbers as parameters. The function will calculate the average of the three numbers and return that average(datatype double) to main.

The program will then print the average of the three numbers from main. The output should include the original numbers and the average (all formatted to two decimal places) and should look something like this:

The average of 4.25, 8.36, and 12.25 is 6.22

Test your program with these numbers:

6.85 5.24 8.64
