    file to array

    I am new to programing and was wondering how to read in a file of integers and then put those integers into an array?

    Too broad of a question, so here's a broad answer. Read a line from the file using fgets. Parse the line using strtod, sscanf, or others.

    Oops. C++ board.

    Same thing, mostly. Read a line using getline (preferably into a std::string). Parse much the same or use std::stringstream.
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
