Question

EDIT: Thanks all of you. Python solution worked lightning-fast 🙂

I have a file that looks like this:

132,658,165,3216,8,798,651 

but it’s MUCH larger (~ 600 kB). There are no newlines, except one at the end of file.

And now, I have to sum all values that are there. I expect the final result to be quite big, but if I’d sum it in C++, I possess a bignum library, so it shouldn’t be a problem.

How should I do that, and in what language / program? C++, Python, Bash?

Answer 1

Python

sum(map(int,open('file.dat').readline().split(',')))
