You are to write a program to calculate the Sample Standard Deviation in C++.

If the number of data points is 4, your program is going to read 4 numbers from the keyboard. Print a meaningful prompt when your program is reading numbers.

After all numbers are read, your program will then calculate the Sample Standard Deviation. Besides the Sample Standard Deviation, your program will also print the average of the data points.

Since we have not learned the looping, you will need to modify your program when the number of data points changes. Before the official input is available, practice modifying your program to fit the changing of the number of data points. Even if you know how to do the looping, looping construct cannot be used in this assignment.
