The average kept coming out wrong.
int add = 0;
float total = 0;
for(i = 0; i < 9; i++) {
       total += array[i ];
       add++;
}

float average = total/9;

why does the average not add up right, im using the basic numbers 1, 2,3, 4, 5, ,6 ,7, 8, 9 so i know the correct average.

You should write it as follows:

int add = 0;
float total = 0;
for(i = 0; i <= 9; i++) {
       total += array[i ];
       add++;
}

float average = total/add;
0

Sorry that was incorrect, it should be:

int add = 0;
float total = 0;
for(i = 0; i < 9; i++) {
       total += array[i ];
       add++;
}

float average = total/add;

>  im using the basic numbers 1, 2,3, 4, 5, ,6 ,7, 8, 9
the ,, between the 5 and 6 would be a syntax error
float average = total/9.0;
or
 float average = (float)total/add;
will do a floating  division rather than an integer division
