[Dev-C++] strcmp

[J H. <jsh...@ho...>]

 i cant figure out how to use the strcmp to compare the string noble to the=
 object helium with the member string name...??!!this is the error that is =
stopping the compiler...44 C:\Dev-Cpp\Untitled1.cpp no matching function fo=
r call to `strcmp(std::string&, std::string&)'  #include <stdio.h>#include =
<iostream>#include <string.h>#include <cstring>using namespace std;struct e=
lements{       string aname;       int atomic_no;       float atomic_weight=
;       }helium, neon, argon, krypton, xenon, radon;     int x;main(){heliu=
m.aname =3D "helium";       helium.atomic_no =3D 2;     helium.atomic_weigh=
t =3D 4;     neon.aname =3D "neon";     neon.atomic_no =3D 10;     neon.ato=
mic_weight =3D 20.1797;     argon.aname =3D "argon";     argon.atomic_no =
=3D 18;     argon.atomic_weight =3D 39.948;     krypton.aname =3D "krypton"=
;     krypton.atomic_no =3D 36;     krypton.atomic_weight =3D 83.80;     xe=
non.aname =3D "xenon";      xenon.atomic_no =3D 54;     xenon.atomic_weight=
 =3D 131.29;     radon.aname =3D "radon";     radon.atomic_no =3D  86;     =
   radon.atomic_weight =3D 222.0176;  string noble; string title("\n\t You =
have selected :\t"); string no("\n\t The atomic number for "); string is(" =
is:\t"); string wgt("\n\t The atomic weight is:\t");printf ("\t The Beginin=
g of the Periodic Table of the Elements \n");printf ("\t In the hopes of le=
arning C programming and elemental values. \n\n\n");cout << "\t Please ente=
r a Noble Gas you would like to examine." ;cin >> noble; if (strcmp (noble,=
helium.aname)=3D=3D0) {            cout << title << helium.aname;          =
  cout << no << helium.aname << is << helium.atomic_no;            cout << =
wgt << helium.atomic_weight;};      cin >> x;      }this is what i have got=
 so far... any help would be appreciatedthanks yohaan
