Hi everybody! I'm new to programming and I've come across a problem when i attempt to do operations on structures. The following line is an example: D = (sumofweights * sum(read_data[].xsq)) - pow(sum(read_data.x), 2); where the function sum() is supposed to sum all the members xsq in the array of a structure: double sum(double array[]){ double result = 0; for(int j = 0; j <= counter; ++j){ /* counter is a variable that updates everytime an . element is added to the structure */ result = result + array[j]; } return(result); } I'm sure there is a syntax error in there or that I'm attempting to do something that isn't allowed, but I cannot for the life of me figure out what it is. Any help would be very much appreciated. Cheers, BBB
