// This program prompts the user for the number of temperatures  they want to input
// and then prompts them for that many temperatures. It then outputs the average
// of all the input temperatures, how many days were above average, 
// all the temperatures the user input, the two lowest temperatures input and 
// the two highest temperatures input

// NOTE: this program has too much code in main! We will talk more about how
//       to use arrays and methods together next class
