Task-1: Write a C++ program that lets a user enter decimal integers for calculating some statistics. Values entered
should be stored in a vector object. The program should present a menu-driven approach in which the inputting

process should continue as long as the user wants. The program should calculate the minimum, maximum, mean,
median, and standard deviation. The program should first sort the list in increasing order to calculate the median.
* The mean formula: i = ÷(E=1*i)
* The standard deviation formula: s =
E=1(xi-x)2
n-1
* For sorting the values entered, you should use the insertion-sort algorithm shown below.
Insertion-Sort(a)
for j e 2 to a.length do
hold + a[j]I
i + j-1
while i > 0 and a[i] > hold do
a[i+1] + a[i]
i + i-1
end-while
a[i+1] € hold
end-for

Procedure: Develop an extension of structure.Vector, called MyVector, that includes a new method, sort. Here are some steps toward implementing this new class:
1. Create a new class, MyVector, which is declared to be an extension of the structure.Vector class. You should write a default constructor for this class that simply calls super();. This will force the structure.Vector constructor to be called. This, in turn, will initialize the protected fields of the Vector class.
2. Construct a new Vector method called sort. It should have the following declaration: public void sort(Comparator c) // pre: c is a valid comparator // post: sorts this vector in order determined by c This method uses a Comparator type object to actually perform a sort of the values in MyVector. You may use any sort that you like.
3. Write an application that reads in a data file with several fields, and, depending

Provide a different implementation of ChoiceQuestion. Instead of storing the choices in a vector, the add_choice function should add the choice to the question text. For this purpose, an add_line function has been added to the Question class.

Member Functions: The class should have functions as follows: Member functions to set and get the month and year variables. A member function that adds a single temperature to the vector. Both negative and positive temperatures are allowed. Call this function AddTemperature. A member function to sort the vector in ascending order.
