For Beginning Java,

"

Write a program that ask the user to enter a list of positive scores until the user enters a negative score to terminate the input.  You need to store these scores in an array.   You can assume the maximum number of scores the user may enter is 70.  However, you need to keep track of the actual number of scores entered.  Write 2 methods:

1. calculateAverage(): this method takes the list of scores and return the average score.

2. countPerfectScores(): this method takes the list of scores and return the number of perfect scores (100).

The main program reads the input and calls these methods and print the results.

Please make sure you write a comment line to document what your method does."

23. Write a program which takes the average of all of the non-negative command line arguments and then prints the result. Your program must call the methods you wrote in the previous questions. For example, if someone runs the program by typing run Midterm 5 6 10 0 -4 into Dr. Java (or java Midterm 5 6 10 0 - 4 from the command line), your program should print 5.25. You may assume that the person running your program types in integers as command line arguments and also that at least one of the numbers typed at the command prompt is non-negative.

Programming section (30 points total) The following code must all go inside of a class called Midterm. 21. Write a method sum which takes as input an array of int and returns the sum of the elements in the array. For example, if the array contains 10 2 3, your method should return 15.

Write a C++ program that takes a vector (with only positive integers) and prints the number of elements in it. [The user will insert any number of elements.]
