Overloading << & >> for an object

[JRimmer]

Microsoft Visual Studio is telling me, with a red squiggly under operator, "Error: too many parameters for this operator function." I looked up how to overload the operators via this link:
(http://stackoverflow.com/questions/4421706/operator-overloading/4421719#4421719)

Following the syntax in those examples isn't fixing the error.

Inside the Set class, .h file is as follows. (prototypes)

//Top of .h file
#include <string>
#include <iostream>

//... More code here
 
//Inside Set Public:
 std::ostream & operator<<(std::ostream&, Set &);
 std::istream & operator>>(std::istream& is, int);

Implementation inside the Set.cpp file, is as follows.

//Already overloaded [ ] to return [x] element of the set
std::ostream & operator<<(std::ostream& os, Set & a){
	
	for (int i = 0; i < a.size(); i++){
		os << a[i];
	}

	return os;
}

Thanks for the help.

try taking making them friend functions and not public members.

Ignore the squiggly lines - actually compile the code, copy and paste the exact error you get, and indicate exactly which line the error is on.

If I move my overloaded operator functions outside my class, or leave them inside with the friend notation in front they work, but with some unexpected residual affects. The >> operator, when overloaded, now doesn't work with the cin statements inside my main function. It says:

" 5 IntelliSense: more than one operator ">>" matches these operands:
function "operator>>(std::istream &is, int)"
function "std::basic_istream<_Elem, _Traits>::operator>>(int &_Val) [with _Elem=char, _Traits=std::char_traits<char>]"
operand types are: std::istream >> int
"

My cout << object; does work now though.

With the two lines (8 and 9) commented out, my program runs without error. With them in, it won't compile giving the following errors:

Error 1 error C2804: binary 'operator <<' has too many parameters
Error 3 error C2804: binary 'operator <<' has too many parameters

This error refers to the call in the main function.
Error 4 error C2679: binary '<<' : no operator found which takes a right- hand operand of type 'Set' (or there is no acceptable conversion)

cout << object;

Thanks for the reply's.

your istream's second parameter should be accepting an object of the class not an int, similarly to the ostream.

Problem solved! Thank you!
