Some Statistical Analysis

Write a program that will calculate and print the sum, mean, variance, and standard deviation of 7 numbers. The numbers must be input as data. This input data must also be printed by the program. Only use what you learned in class so far; no arrays, functions, objects, etc.

Further instructions:  If your seven numbers input have been named A, B, C, D, E, F, G, then the variance may be computed as:

variance = [(A-mean)2 + (B-mean)2 + ... + (G-mean)2]/6

and the standard deviation is the square root of the variance. (Hint: If you can't figure out how to get the square root in C++ leave it out at first.  You can always add to your program later, once it works without it.)

Run your program three times, using three different sets of data:

Run I: 12, 22, 34, 43, 45, 54, 99

Run II: 1.0, 1.5, 2.5, -9.3, 0, -1.0, 3.0

Run III: Any 7 numbers of your own choosing.
