Problem 1: 30 The Relief Cause, a charitable relief agency, solicits donations from businesses. The local office received the following donations from the employees of UWGB: $5, $100, $5, $25, $10, $5, $25, $5, $5, $100, $10, $15, $10, $5, $10, $25, $45, $15 The donations were received in the order they appear. The relief agency's manager has asked you to write a program that displays the donations in ascending order, as well as in their original order. For this program, use the supplied code in donations.cpp file. The program is written with some code segments missing which you need to complete. You need to write code and finished this partially completed program and run it successfully error-free. Your code segment will go in place where you see the following text /* Write your code here*/ Any place within the file you this text, this means you have to include code that will perform the required function(s) mentioned in the preceding comment(s). You also need to complete to functions (showArray, and showArrPtr) whose prototypes are declare in the file. The output of the completed program will be like the following: The donations, sorted in ascending order are: 5 5 5 5 5 5 5 10 10 10 10 10 15 15 25 25 25 45 100 100 The donations, in their original order are: 5 100 5 25 10 5 25 5 5 100 10 15 10 5 10 5 10 25 45 15 Problem 2: 40 Write a program that can be used to gather statistical data about the number of movies college students see in a month. The program should perform the following steps: Ask the user how many students were surveyed. An array of integers with this many elements should then be dynamically allocated. Allow the user to enter the number of movies each student saw into the array. Calculate and display the average, median, and mode of the values entered. . O In statistics, when a set of values is sorted in ascending or descending order, its median is the middle value. If the set contains an even number of values, the median is the mean, or average, of the two middle values. The function should determine the median of the array. This value should be returned as a double. In statistics, the mode of a set of values is the value that occurs most often or with the greatest frequency. Your function should determine the mode of the array. That is, it should determine which value in the array occurs most often. The mode is the value the function should return. If the array has no mode (none of the values occur more than once), the function should return -1 and mode is unavailable. You need to use pointer notation instead of array notation. Input Validation: Do not accept negative numbers for input. Problem 3: 30 As programmer, the local retail store asked you to develop a function named formatDollar that inserts commas and a $ sign at appropriate locations in a string object containing an unformatted dollar amount. As an argument, the function should accept a reference to a string object. You may assume the string object contains a value such as 1084567.89. The function should modify the string object so it contains a formatted dollar such as $1,084,567.89. Similarly 425389.35 will be formatted as $425,389.35. For this problem, use the supplied currency.cpp file and modify/insert your code to complete the task and generate the following output Enter a dollar amount in the form nnnnn.nn : 45879357.322 Here is the amount formatted: $45,879,357.322 Hint: Use string class find () method to find the occurrence of the decimal point
