Re: [Boost-users] [Boost.StringAlgo] How to insert substr into str

Hi, Valentine Rozental wrote:

Dear All,

what is the elegant/right way to insert some substr into the given str? For example:

// ------------------------------------------------------- ... std::string str("xyz_123_abc_xyyz_a1b"); std::string mark("abc"); std::string substr("$$$");

iterator_rangestd::string::type> it1 = boost::find_first(str, mark); ... // -------------------------------------------------------

I want to insert substr ("$$$") after mark ("abc") if the mark exists in the str. That is, the result in the example above should be: "xyz_123_abc$$$_xyyz_a1b"

Thank you in advance!

If you are using std::string, why could simply type if(it1) { str.insert(it1.end()-1, mark); } Regards, Pavol.
