error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' (
or there is no acceptable conversion)
Error executing cl.exe.


I keep getting that error when I try to cout a array from a structure. This is the piece of code.
----------------------------
#include <iostream.h>
#include <string>
using namespace std;


struct record{
      int key;
      string firstName;
      string lastName;
      int studentid;
      int courseID;
      string coursename;
      double courseMark;
};



string Getfirstname();


int main(void)
{
      
      record Database[100];//reserve memory for 100 records
      int i=0;
      char reply;

      do{
                  
      Database[i].key=i;
      Database[i].firstName=Getfirstname();      
      
      cout<<"\nwould you like to enter another student in the database? (y) or (n) ";
      cin>>reply;
      
      
      }while(reply=='y');
            
      cout<<Database[0].firstName; //THIS LINE ERROR
   

      
return 0;
}


string Getfirstname(void){
char firstName[50]; string final;
cout <<"\nplease enter the number of hours worked ";
cin.getline(firstName,50);
final.assign(firstName);
return firstName;
}

--------------------------------------

Anyone got any suggestions please.

Drop the .h from iostream.h:

thank you a lot. Do you know why I had to remove the h from the input/output class ?

The simple answer is because it's in the standard

It centres around the std namespace. Don't mix and match the old and new headers.

I've often seen this:

namespace MyNS
{
#include <map>
}

and it confuses the compiler big time.
