Hello, there is a string

string str="go hi . uyyuer";

How can you find a character in this line, let's say "." and then copy it?

As a result, to get this:

 str="go hi .. uyyuer";

Thank.

     str.insert (str.find("."), ".");

    PS General option:

     for (int i = 0; i < str.length()-1; i++) if (str.at(i) == '.') str.insert (i++, ".");

    It is possible to try through STL somehow.
