MUST BE WRITTEN IN C++ Write a program so that user can use it to compute and display various statistics for a list of at least 3 values and up to 20 positive real values. The main objectives of this project are to work with menu, arrays, file input, and modules/functions. A menu is available and user can select one of the 4 options from the menu. The program will continue until option 4 is selected. For option 1, process a predefined array in the code with 3 values (73.3 83.4 58.0). User will be able to input an array from the keyboard with a sentinel loop with option 2. Use the following values (73.3 83.4 58.0 11.9 25.1 69.9 45.7 95.0 44.4)as one of your test cases (use -1.0 as a sentinel value). When option 3 is selected, input data from a text file. Use the given p2input.txt Download p2input.txt as a test case. The values in the file are shown below. 73.3 99.0 83.4 58.0 25.1 69.0 11.9 95.0 74.8 55.0 43.5 47.4 95.6 58.9 52.6 37.7 93.8 19.9 23.9 77.2 You can assume that the user will provide a list of valid values (i.e., valid values, provide a list with at least 3 values and will not exceed the maximum number of values). After receiving a list of values via one of the options, your program shall display the original array with maximum 5 values per line, sorted array in descending order with maximum 6 values per line, maximum, average, median (only one median value is needed; need to deal with odd or even list), and sample standard deviation in a readable format using one digit after the decimal place. The sample standard deviation formula, is s=i=1N(xi-x N-1, where xi is the ith element in a list, x is the average of the values in the list, N is the number of values in the list, and s is the sample standard deviation. If you need assistance with this formula, please ask. Make sure to come up with a solid design before attempting your code on the computer. You should use a global named constant to deal with maximum number of values. You must utilize some modules/functions in your program and the following modules/functions should be incorporated in your program. However, the seven modules/functions in bold are required for the project (i.e., you must have at least five required modules/functions to get full credit). In general, it does not make sense to print a result in a Math-like function (a function that calculates a value such as average) so it just returns a value and let the caller handles the result. It doesn't make sense to print in a sort module either because its main job is to sort a list of values. You must use the same printList() module to print both the original array and the sorted array (call twice from main). We assume that an array is automatically passed by reference so "Ref is not included when designing modules/functions. Display menu and return a valid option Function Integer getMenuOption() Input a list of values from keyboard Module inputList(Real arr).
