    find string function

    hi,

    in a program, i currently have:
    Code:
    string line, hey(" hey ");
    getline(cin, line);
    line.find(hey, 0);
    which will as ask for a line of input and will then search the line for the word hey surrounded by a space on each side.

    so far the find function only searches once starting at the begining of the string. how can i modify it to keep finding more than one occurance of " hey " ?

    thanks,
    barneygumble742

    In general, you can do it like this using the find method...
    Code:
        for (string::size_type pos = 0;
             (pos = line.find(hey, pos)) != string::npos;
             ++pos)
        {
            cout << "found occurrence starting at " << pos << endl;
        }//for
    gg
