Question

Programming in C#: Write a console-based application that displays every perfect number from 1 through 10000. A number is perfect if it equals the sum of all the smaller positive integers that divide evenly into it. For example, 6 is perfect because 1, 2, and 3 divide evenly into it and their sum is 6. Use format strings(field size 8, right alignment) to show all perfect numbers. Display the results as seen below. 6 28 496 8128

Question

Chapter 12, Problem 15PP

Program Plan Intro

Display student class details “HashMap” and “ArrayList”

Program Plan:

Import required package.

Define “StudentIDsListTest” class.

Define main function.

Create hashmap for student ID and course number.

Create an object for scanner class.

Declare required variables.

Display prompt statement.

Performs “do-while” loop. This loop will execute until “studID” is not equal to “-1”.

Read student ID from user.

If student ID is not equal to “-1”, then read course number from user.

If the student ID is contains in “students” list, then

Create array list named “class_List”.

Add the course number to “class_List” using “add” method.

Map the student ID to course number using “put” method.

Otherwise,

Create array list named “class_List”.

If the course number is not in the class list, then add the given course number to “class_List” using “add” method.

Display all the classes for each student using “for” loop.

Create array list named “stud_List”.

Display course number for corresponding student ID.

In C Programming Language Palindrome: “A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward, such as ‘madam’ or ‘kayak’” (excerpt from Wikipedia).Write a program that reads 8 words from Palindrome.txt and checks whether the word you read is a palindrome (please read its description above) or not. Print the index numbers of all the palindrome words in your array. You are required to read words character by character into a character array.• Write readFile function, which gets a file pointer and a two-dim array, to read each word(bunch of characters) line by line and store them into a two-dim character array.• Write findSize function takes a one-dim array and returns its actual size.• Write isPalindrome function takes a one-dim character array to check whether the content is a polindrome or not. If the word (character squence) is a palindrome, then it returns 1. Otherwise, it returns 0.

The mean of a list of numbers is its arithmetic average. The median of a list is its middle value when the values are placed in order. For example, if an ordered list contains 1, 2, 3, 4, 5, 6, 10, 11, and 12, then the mean is 6, and their median is 5. Write an application that allows you to enter nine integers and displays the values, their mean, and their median.
