Complete the functionality number 3 and 6 below of a menu-driven procedural C++ program that shows on the console statistic values from a series of 3 real values inserted by the user. Use as starting point the program prototype below. BASIC STATISTIC CALCULATOR:

1.- Insert Series

2.- Minimum

3.- Maximum

4.- Sum

5.- Arithmetic Mean

6.- Standard Deviation

7.- Full Report

8.- Show Series

0.- Quit

Template below-
