    ifstream and ofstream

    I'm reading this tutorial:
    http://www.cprogramming.com/tutorial/lesson10.html

    I have found this a little bit challenging. Can anyone expound to me what it means technically.
    I'm a python programmer and would like to add C++ and take advantage of ctypes and also I learn myself.

    Thanks for your help.

    So, could you be a bit more specific as to which part of the tutorial you do not understand?

    Compilers can produce warnings - make the compiler programmers happy: Use them!

    How good are you with cin and cout? File streams are supposed to work pretty much exactly the same way.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    In python it is as simple as:
    fo = open("steve.txt")
    for words in fo:
    print words

    it will print all words in text files. I was wondering how easy it is in C++

    Code:
    #include <fstream>
    #include <iostream>
    
    int main()
    {
       return(!(std::cout << std::ifstream("test.cxx").rdbuf()));
    }

    Well, that is the equivalent of

    Code:
    print open("test.cxx").read()
    in Python.

    Use getline(input_stream_object, string_object) to read a line of input, just as you would do with cin.

    Code:
    ifstream fin("test.cxx");
    std::string line;
    while (std::getline(fin, line)) {
        std::cout << line << '\n';
    }
