    Having trouble multiplying these arrays...

    This is really the only segment of code that matters

    Code:
    for (i=0; i<length; i++) {
            for (c=0; c<length; c++) {
                 product[i] = a[i]*a[c];
            }
        }
    I'm trying to multiply the arrays by each other (for example if the array a is [4,6,8] and array b is [5, 7,9] then I want the product array to = [4x5, 6x7, 8x9])
    But it is multiplying them some other way and when I try to do it by hand I only get the answer I think is right , not the one the computer gives. If the rest of the program would help I can post that too thanks.
