// Program: Gradebook Application
// Author:
// Date: 04/27/2012
// Purpose: the purpose of the program is use an array of strings objects the
// hold five students names, an array of five characters to hold the five
// students letter grades and five arrays of four doubles so each students set
// of test scores. The program should allow the user to enter each student's
// name and his or her for test scores. The program will calculate and display
// each student average and a leeter grade based on the average.
// *****************************************************************************
# include <iostream>
# include <iomanip>
using namepace std;
// Function prototypes
void getTestScores(double[],int);
void getStudentName(string[]);
double getTotal(const double [], int);
double getLowest(const double[],int);
int main{}
{

string studentName[SIZE]; // Array of student names
double testScores[SIZE]; // Array of test scores
total, // Total of the scores
lowestScore, // Lowest test score

// setup numeric output formatting.

//Get the student name from the user.

// *****************************************************************************
// The getTestScores function accepts an array and size has arguments.
// It promptly uses energy test scores, which are stored in the array.
