How to calculate the average of scores?

[david.jones]

Hey guys, for some reason I can't figure out how to calculate the average from a number of scores in an array.

I've tried although I get weird numbers e.g 1003434343.43 or inf. Here's my attempt:

//avg score
   for (index = 0 ; index < score[index] ; index++)
       {
         avgScore = (avgScore + score[index] / index);
       }

Need the rest of your code. Please post compilable code.

Is avgScore initialized? Is it a float? An int?

See what I mean?

What you want is to sum all elements in the array, then divide by the amount of elements. So the general case would look something like this:

for(i = 0; i < array_size; i++) {
    sum += array[i];
}

average = sum / array_size;

Well this is going to be division by zero on the first pass.

First you calculate the total, with say
total = total + score[index];


Then you calculate the average
average = total / n;

Just sumarise all of your scores and divide the result by their number.
