    String/Data Manipulation

    I have some data in the following format:

    gggg@ gggggggg gggggg ggggggggg
    trrehd@ dffdhghtr rggffrg nhgvhvgnhgyy
    po@ dkjfkdg gfdkjhjdkhf dgfgfffff ffff
    ppppppoppo@ dsgjhfdkhvc gfdkjhgkj kjhgkf

    Now I want to output the data that comes after the '@' for each line. Any help is much appreciated!

    Check out the getline command

    I'm using the Win API and because of that I can't use getline().

    I assume the data are saved on a file and you are trying to read the data into memory.

    -----
    // std::getline(sourcefile, string);

    // this should return the index of "@"
    // int index = string.find('@');

    // for (int i = ++index; i < string.size(); ++i)
    // cout << string[i]
    -----

    The code above is a concept. You should modify it to fit your need and to optimize your program.

    windows API and STL are not mutually exclusive. You can use getline just fine.

    I've been unable to get the getline() function to work. Any suggestions?

    I've tried the following:
    Code:
    getline()
    std::getline()
    ifstream::getline()
    : error C2065: 'getline' : undeclared identifier

    What header files have you included. Sounds to me like you are leaving one out.
