					LAB 7

Purpose: This lab is to introduce you to programming in C with
user defined functions and to call by value.

Please write a relatively simple C program which will use a
main function and two additional functions to input four floating
point values, average them, and output the average.

The main function should prompt the user for the four values
and input these from the keyboard.  The first additional function
should average these four values and return the average value. 
The second additional function should output this calculated
average, appropriately labelled.

If this required work is completed before the end of the lab
period, modify the program to produce and output the average, the
variance, and the standard deviation of these values (all in one
program).
     
The formula for Variance is given in Exercise 10 on Pg 263
of the text.  The Standard Deviation is the square root of the
Variance.
