Re: reading a file into std::string

you mean this code will be real-life code based on the ideas you have
given me:

#include<iostream>
#include<fstream>
#include<string>

int main()
{
   std::ifstream my_file("reference.cpp");
   if(!my_file)
     {
       std::cerr<< "Error Opening file"<< std::endl;
       exit(EXIT_FAILURE);
     }

   std::string my_contents(std::istreambuf_iterator<char>(my_file.rdbuf()),
              (std::istreambuf_iterator<char>()));

   std::cout<< "String contents are:"<< "\n"
    << my_contents<< std::endl;

   my_file.close();

   return 0;
}

as usual compiled with "gcc -ansi -pedantic -Wall -Wextra" and it
compiles and runs fine.
