Write a program that calls a function calculateSum to calculate the sum from 0 to N integers. The function calculateSum has one parameter N of type integer and returns an integer which represents the sum from 0 to N, inclusive. Write another function calculateAverage that calculates an average. This function will have two parameters: the sum and the number of items. It returns the average (of type float). The main function should be responsible for all inputs and outputs. Your functions will only calculate and return the values and NOT print anything. N is provided by the user; user input must be asked for repeatedly until a non-negative integer is provided.

Acolor class has three public, integer-returning accessor methods: getred, getgreen, and getblue, and three protected, void-returning mutator methods: setred, setgreen, setblue, each of which accepts an integer parameter and assigns it to the corresponding color component. the class, alphachannelcolor-- a subclass of color-- has an integer instance variable, alpha, containing the alpha channel value, representing the degree of transparency of the color. alphachannelcolor also has a method named dissolve (void-returning, and no parameters), that causes the color to fade a bit. it does this by incrementing (by 1) all three color components (using the above accessor and mutator methods) as well as the alpha component value. write the dissolve method.
