//      Due date:       Wed., Feb. 20, 2008
//      Compilation:    g++ assign3.cpp -o assign2.out
//      Execution:      ./assign3.out
//
//      Goal: This program will allow the user to input students'
//      information (name, age, test1, test2, and final), and output each
//      student's average, class average, and the average age of students
