    String Iterators

    Am in need of some help with a string iterator.

    Basically I want to set the iterator to a particular location of a string, such as that returned by the string::find() function.

    Any help would be greately apreciated.

    string::find() returns an interator, just do an assignment with the return value.

    >>string::find() returns an interator,
    No,string::find returns string::size_type.

    You can do this
    Code:
    string::size_type st = str.find("...");
    string::iterator strIter = str.begin();
    strIter += st;

    You're right, I was thinking of the generic find from <algorithm>.

    Thanks for that.

    incrementing the iterator by the number of possitions relative to the start worked.
