Write a C++ program that will read monthly sales into a dynamically allocated array. The program will input the size of the array from the user (must be less than or equal to 12). It will call a function that will find the sum of all sales. It will also call a function to find the average. It will also call a function to sort the array using either a bubble or selection sort in descending order and then display the results. You must have a comment block header at the top of your program. See the Standards document in Course ContentYou must use pointers for your arrays and dynamically allocate them based on the number of monthYou must remove and reset the array when completedYou must use the correct data types for your variablesYou must validate your input. The number of months must be between 1 and 12You must use a loop to read in the salesYou must use at least 3 functions to calculate the average, sort the array and display the salesYour output should be formatted correctlySales totals, average should have two decimal places Sample Run #1:Please input the number of monthly sales to be input 4Please input the sales for month 1: 1290.89Please input the sales for month 2: 905.95Please input the sales for month 3: 1567.98Please input the sales for month 4: 994.83The total sales for the time period is $4759.65The average month sale is $1189.91Sales in descending order: $1567.98$1290.89$994.83$905.95Sample Run #2:Please input the number of monthly sales to be input 0You must enter a value between 1 and 12.

Question

Write a C++ program that will read monthly sales into a dynamically allocated array. The program will input the size of the array from the user (must be less than or equal to 12). It will call a function that will find the sum of all sales. It will also call a function to find the average. It will also call a function to sort the array using either a bubble or selection sort in descending order and then display the results.
- You must have a comment block header at the top of your program. See the Standards document in Course Content
- You must use pointers for your arrays and dynamically allocate them based on the number of month
  - You must remove and reset the array when completed
- You must use the correct data types for your variables
- You must validate your input.
  - The number of months must be between 1 and 12
- You must use a loop to read in the sales
- You must use at least 3 functions to calculate the average, sort the array and display the sales
- Your output should be formatted correctly
  - Sales totals, average should have two decimal places
Sample Run #1:

Please input the number of monthly sales to be input
4
Please input the sales for month 1:
1290.89
Please input the sales for month 2:
905.95
Please input the sales for month 3:
1567.98
Please input the sales for month 4:
994.83
The total sales for the time period is $4759.65
The average month sale is $1189.91
Sales in descending order:
$1567.98
$1290.89
$994.83
$905.95

Sample Run #2:

Please input the number of monthly sales to be input
0
You must enter a value between 1 and 12. Please reenter.
Please input the number of monthly sales to be input
14
You must enter a value between 1 and 12. Please reenter.
Please input the number of monthly sales to be input
2
Please input the sales for month 1:
959.44
Please input the sales for month 2:
674.11
The total sales for the time period is $1633.55
The average month sale is $816.78
Sales in descending order:
$959.44
$674.11
