    Splitting a huge string in several smaller strings

    Hello everyone, this is my problem:

    I have a .txt file with a huge string of names, seperated like this:

    "BELLA, "JONATHAN", ...

    I need to operate on each name, so I want to store them in a vector, but without the " and , characters. I've made an algorithm, but it seems there is no easy way to do this:

    - take note of first index of name
    - check for next index until you hit a "
    - cut of the string from index i till i + j

    I thought of storing all seperate characters of a single name in a temporary vector<char>, then compiling those characters in a string with a for loop, is this possible?

    Thanks in advance!

    Here is an easier way:
    1.Use std::getline with the delimiter ',' and looping to the end to get the strings with the quotes, into a std::vector<std::string>.
    2.Use std::string's substr function on each string to prune the quotes.
    (You can easily combine the steps..)

    std::vector<std::string> Names;
    boost::split(Names, MyHugeString, boost::is_any_of(","));
