create a program based on the following pseudocode:

• put the usual three comments at the beginning: your name, the date, and the program's name, which is snowfall
• your program will allow the user to enter the number of inches of snow that fall during a user-defined number of days
• dynamically allocate an array large enough to hold those days
• once all of the inches of snow, which may be any number from zero and up, the array should be passed to a function that sorts them in descending order of inches
• another function should be called that calculates the average number of inches of snow per day
• your program should display the sorted list of snow inches and snow average with appropriate headings
• use pointer notation rather than array notation whenever possible
• input validation: do not accept zero or negative numbers for number of days
• input validation: do not accept negative values for snow inches
