Thread: need help with overloading << , please

Hello , when I try to compile the following code the compiler gives me the following error :
error C2804: binary 'operator <<' has too many parameters

the code makes no sense , I just wanted to learn how to use the overloading with any kind of program. Here is the code :

Code:

#include <iomanip>
#include <iostream>
#include <ostream>
#include <fstream>
#include <string>

using namespace std;

class name{

public:
	void display(void);
	void assing(string t1,string t2);
 ostream & operator<< (ostream &k , name &obj){

	k<<obj.d1<<obj.d2<<endl;
	}

private:

	string d1,d2,d3;

};



void name::assing(string t1,string t2){
	d1=t1;
	d2=t2;
}
void name::display(void){
	cout<<d1<<endl<<endl;
	cout<<d2<<endl<<endl;

}

int main(){
	string s1="aaa", s2="bbbb";
name c;
 c.assing(s1,s2);
cout<<c;

	return 0;


}

Thank you.

sorry I forgot to include the return k; , but even returning it gives me the same error.

operator << needs to be made a friend function and defined outside of the class. The error you are getting is because you are trying to define the operator<< function that lets you do something like:

Code:

 Obj obj;
obj <<"Hello World";

Simply change it to:

Code:

friend  ostream & operator<< (ostream &k , name &obj);

and outside the class put the function.

Thantos Thank you , I solved my problem with your help.
