/*P3Q2
 * Wang Chaoran
Description:2 (Counting positive and negative numbers and computing the average of numbers)
Write a program that reads an unspecified number of integers,
determines how many positive and negative values have been read,
and computes the total and average of the input values, not counting zeros.
Your program ends with the input 0. Display the average as a floating-point number.
(For example, if you entered 1, 2, and 0, the average should be 1.5.)
