/*
Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped.

It should use the following functions (for you to code):

•  double getScore() should ask the user for a test score, store it in a variable, and validate it.  If valid, return the score, otherwise return -1.
•  This function should be called by main until each of the five scores are valid.
•  void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by  main and should be passed the five scores.
•  int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage , which uses the function to determine which of the five scores to drop.

Input Validation: Do not accept test scores lower than 0 or higher than 100.
