I asked this once before but it came up incorrect somehow so I'll submit this one again. Write a program in C# named ArrayDemo that stores an array of 10 integers. (Note that the array is created for you and does not need to be changed.) Until the user enters a sentinel value, allow the user four options: (1) to view the list in order from the first to last position in the stored array (2) to view the list in order from the last to first position (3) to choose a specific position to view (4) to quit the application. -------- using System; using static System.Console; class ArrayDemo {    static void Main()    {        int[] nums = {7, 6, 3, 2, 10, 8, 4, 5, 9, 1};        // Write your main here    }   }

In C++ Create an array of 100 random numbers between 1 and 1000. Ask the user for a number. Search the array and check if the users number is in the array.
Assignment 5A: Multiple Frequencies. In the last assignment, we calculated the frequency of a coin flip. This required us to have two separate variables, which we used to record the number of heads and tails. Now that we know about arrays, we can track the frequency of all numbers in a randomly generated sequence. For this program, you will ask the user to provide a range of values (from 1 to that number, inclusive) and how long of a number sequence you want to generate using that number range. You will then generate and save the sequence in an array. After that, you will count the number of times each number occurs in the sequence, and print the frequency of each number. Hints: You can use multiple arrays for this assignment. One array should hold the number sequence, and another could keep track of the frequencies of each number. Sample Output #1: What's the highest number you want to generate?: 5 How Long of a number sequence do you want to generate?: 10 Okay, we'll generate 10…

TRUE or FALSE IN JAVA You can obtain the number of rows using Array.length, and the number of columns in a specified row using array[row].length.
Using c++ write a program Program : Date Printer Write a program that reads a char array from the user containing a date in the form mm/dd/yyyy. It should print the date in the form March 12, 2014. For example Enter Date 5/14/2019 May 14, 2019 Validation Required: Month should be less than 13, day should be less than 31.
In C++Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 × 5 array, where each row represents a different monkey, and each column represents a different day of the week. The program should first have the user input the data for each monkey. Then, it should create a report that includes the following information: Average amount of food eaten per day by the whole family of monkeys. The least amount of food eaten during the week by any one monkey. The greatest amount of food eaten during the week by any one monkey. Write functions: average() least() greatest() main()
Median Function – In statistics, the median of a set of values is the value that lies in the middle when the values are arranged in sorted order. If the set has an even number of values, the median is the average of the two middle values. Your program should start with two arrays of integers containing the following values: Even numbered array: 17 32 45 68 99 101 67 89 22 27 Odd numbered array: 17 32 45 68 99 101 67 89 22 Using a sort function of your choice, first sort the arrays. NOTE: you may use the Standard Template Library sort function or your own sort function. Then, write a function that determines the median of a sorted array. The function should take an array of numbers and an integer indicating the size of the array and return the median of the values in the array. The same function should be called twice – once for the even array and once for the odd array. Your program should also have a printArray function that can be used to print the sorted array. (It…
