you will write a c++ program to input 5 elements (of type int) from the user and store them in an array. Your program should then reverse the array and display it. For instance, if the user enters 1 2 3 4 5 as the five elements of the array, your program should reverse it and display: 5 4 3 2 1 Note: You must use a for loop to process the array.
To what is the term “base address of an array” refer, and how is it used in a function call?
how can i store a user input by using arrays in c++? can i have an example??? thank you
(Flattening arrays with flatten vs. ravel) Create a 2-by-3 array containing the first six powers of 2 beginning with 2^0. Flatten the array first with method flatten, then with ravel. In each case, display the result then display the original array to show that it was unmodified. Please use Python and keep it simple.

C++ ONLY PLEASE, and please read carefully, i have had people submit wrong answers Assignment 7 A: Rare Collection. We can make arrays of custom objects just like we’ve done with ints and strings. While it’s possible to make both 1D and 2D arrays of objects (and more), for this assignment we’ll start you out with just one dimensional arrays. Your parents have asked you to develop a program to help them organize the collection of rare CDs they currently have sitting in their car’s glove box. To do this, you will first create an AudioCD class. It should have the following private attributes.  String cdTitle  String[4] artists  int releaseYear  String genre  float condition Your class should also have the following methods:  Default Constructor: Initializes the five attributes to the following default values: ◦ cdTitle = “” ◦ artists = {“”, “”, “”, “”} ◦ releaseYear = 1980 ◦ genre = “” ◦ condition = 0.0  Overloaded Constructor: Initializes the five attributes based on values passed…
I want to know how to write this C++ code with comments to help me understand better.
Please use easy logic with proper indentations and comments for understanding!. Coding should be in C++. 3. Define a class which stores up to 10 integer values in an array. The class should also define the following 4 public methods: setNumber – accepts an integer value to store in the array. The value is stored in the next available element of the array (first call to the method stores the value in element 0 with the second call storing the value in element 1.) The method returns true if there is room in the array and the integer was successfully stored. Returns false otherwise. clear – removes all values from the array so that the array can be reused. displayNumbers – displays the values currently stored in the array. getStats – determines the largest, smallest, and average of the values currently stored in the array. These values are returned to the caller via reference parameters. All methods should produce correct results regardless of the order in which…
