    std::stringstream

    Consider this piece of code:
    Code:
    std::string S = "1 2 3";
    std::stringstream SS(S);
    int I;
    SS >> I;
    std::cout << SS.str().c_str();
    After extracting an integer from the stream you will still get the entire stream when calling .str(), meaning "1 2 3". Is there some easy way of retrieving what's left in the stream, in this case "2 3"?

    Here's one way:
    Code:
    std::string remains;
    size_t avail = SS.rdbuf()->in_avail();
        
    // assign(source string, offset, count)
    remains.assign(S, S.length() - avail, avail);
    
    std::cout << "Remaining: \"" << remains << "\"" << endl;
    gg
