    "datastream" class

    This isn't too useful (and there might be a standard STL that does this anyway), but this might make coding more convenient.

    When you pass this object data, it uses sprintf to convert it to a string.

    Code:
    datastream x;
    x << 5;
    int y;
    x >> y;
    That basically would assign y the value of 5.

    You can use the indexing operators, cout it, cin to it... ifstream, ofstream...

    Enjoy! Its not very complex, but it could be useful (if there is a built in one, please tell me so I can look it up)

    There is a built-in object that is called std::stringstream in the <sstream> header.
    It reads and writes data to and from a string.

    how do you use it, and does it let you search using the indexing op?

    datastream x = 12345;

    x[x["23"]] will work, as long as 23 is found
