Habe dies jetz geändert das resultat bleibt leider gleich

#include <iostream>
#include <string>
#include <fstream>
#include <cstdlib>
#include "include/libhtml++.h"

using namespace std;

std::string htmlformselect::anfrage(std::string methodform )
{

char* buffer = 0; 
unsigned int len;

if (methodform == "GET")
{
len = strlen(getenv("QUERY_STRING")); 
     buffer = new char[len+1]; 
     strcpy(buffer,getenv("QUERY_STRING"));
}

else if (methodform =="POST")
{
 len = atoi(getenv("CONTENT_LENGTH")); 
     buffer = new char[len+1]; 
     for(unsigned int i=0; i<len; i++) 
     cin.get(buffer[i]);
}

buffer[len] = 0;

formselectoutput = buffer;
delete[] buffer;
return formselectoutput;
}

Vielleicht liegt es ja an dieser funktion:

#include <iostream>
#include <string>
#include <fstream>
#include <stdio.h>
#include <cstdlib>
#include "include/libhtml++.h"

using namespace std;


void htmlformselect::formselectdisplay (std::string formselectname, std::string formselectinput, std::string methodform)
{

formselectinputprint = formselectinput;

     int pos = 0;
     do
     {
          pos = formselectinputprint.find("[F]");
          if(pos != string::npos)
                formselectinputprint.replace(pos,strlen("[F]"),"<option>");
     }
     while(pos != string::npos);

     do
     {
          pos = formselectinputprint.find("[/F]");
          if(pos != string::npos)
                formselectinputprint.replace(pos,strlen("[/F]"),"</option>");
     }
     while(pos != string::npos);

cout << "<select name=" << '"' << formselectname << '"' << formselectinputprint << "method=" << '"' << methodform << '"' << "action=" << '"' << "http://tuxist.de/cgi-bin/index.cgi" << '"' << ">" << endl;
}
