std::string error combining *RESOLVED*

[The_Dragon]

Ok i've a problem when using this code

#include <iostream>
#include <string>
using std::cout;
using std::string;

int main()
{
  string recbuffer;
  string endmsg1 = (char)(10);
  string endmsg2 = (char)(13);
  recbuffer += "NICK The_Dragon" + endmsg1 + endmsg2;
  cout << recbuffer;
}

it's supposed to display "NICK DBZ_Dragon ASCII(10) ASCII(13) but it ends up giving an erro at string endmsg1... and endmsg2... so what am i doing wrong... im still fairly new to c++
