i am on a unixlike system. i have a file of numbers, one on each line. i want the sum of these numbers. how do
@ky0ko Here are a couple of methods in bash, bc, and awk, which I *think* could be adapted to one on each line: https://stackoverflow.com/questions/2572495/read-from-file-and-add-numbers
You could also go the C route, open the file, read each line into one array (char**), use atoi (or atof or whatever) to get another array of actual numbers, then sum over that array.
