Create a program that contains 4 methods / functions... main(), getTestScores(), calcAverage(), and displayAverage(). The main() method should call the getTestScores() method to get and return each of 3 test scores. The main function should then call the calcAverage() method to calculate and return the average of the three test scores. The main() method should then call the displayAverage() method to display the average of the test scores.
