#### 10.10.2 Pretty-Printer Example

Here is how a C`++` `std::string` looks without a pretty-printer:

    (gdb) print s
    $1 = {
      static npos = 4294967295,
      _M_dataplus = {
        <std::allocator<char>> = {
          <__gnu_cxx::new_allocator<char>> = {
            <No data fields>}, <No data fields>
          },
        members of std::basic_string<char, std::char_traits<char>,
          std::allocator<char> >::_Alloc_hider:
        _M_p = 0x804a014 "abcd"
      }
    }

With a pretty-printer for `std::string` only the contents are printed:

    (gdb) print s
    $2 = "abcd"
