Please help with my C++Specifications • For the view and delete commands, display an error message if the user enters an invalid contact number. • Define a structure to store the data for each contact. • When you start the program, it should read the contacts from the tab-delimited text file and store them in a vector of contact objects. •When reading data from the text file, you can read all text up to the next tab by adding a tab character ('\t') as the third argument of the getline() function. •When you add or delete a contact, the change should be saved to the text file immediately. That way, no changes are lost, even if the program crashes later
The program will consist of two files Program.cs - the main application file; name the class appropriately Unique.cs - class for retrieving the unique values from the user The Unique class provides the following: Constructor Private member variable to store 5 unique values (hint: use an Array or a List) Public function to get 5 unique values from the user and store them in the member variable loop to get the numbers, if a number is already stored, ignore it and keep looping until you have 5 unique numbers if a number is out of range, don't store the value, throw an exception and handle it in such a way that you don't break the loop but do message the user that the value was out of range Public functions to return the following based on the stored values: Largest number Smallest number Sum of all numbers Average of the numbers entered Last number entered divided by the first number entered The main application does the following Creates an instance of the Unique class Calls…
createDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).
