Chapter 3.10, Problem 3.31CP
Assume the following variable declaration exists in a
double number = 123.456;
Write a statement that uses System.out.printf to display the value of the number variable padded with leading zeros, in a field that is eight spaces wide, rounded to one decimal place. (Do not use comma separators.)

Computer Fundamentals and Programming 2
Write a program that determines a student’s grade. The program will accept 3 scores and computes the average score. Determine the grade based on the following rules:
- If the average score is equal or greater than 90, the grade is A.
- If the average score is greater than or equal to 70 and less than 90, the grade is B.
- If the average score is greater than or equal to 50 and less than 70, the grade is C.
- If the average score is less than 50, the grade is F.

The Problem__:
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:
⚫ void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered.
⚫ 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.
YOU MUST USE THE STATED FUNCTIONS AND COMPLETE Input VALIDATION.
**DO NOT use an ARRAY OR GLOBAL VARIABLES!!.
you MUST USE function prototyping
TEST THE FUNCTION TWICE.…
