For this task you have the chance to show what you’ve learned about implementing repetition in code. You are required to create a program that uses the while loop structure.
Write a program that always asks the user to enter a number. When the user enters the negative number -1, the program should stop requesting the user to enter a number. The program must then calculate the average of the numbers entered excluding the -1.
Make use of the while loop repetition structure to implement the program.
