C :: Count How Many Negatives And Positives Are Based On Users Input

I just don't understand how you would have it count how many negatives and positives there are based on the user's input? Here's the problem and the code it provides:

Modify the program so that is displays the average of the positive and negative numbers. (Hint: be careful not to count the number 0 as a negative number.)

Code:

#include <stdio.h>
#define MAXNUMS 5
int main() {
int i;
float number;
float postotal = 0.0f;
float negtotal = 0.0f;
