Newbie help please

Hello everyone, I am new here and I was wondering if anyone could please give me some help!...I have a program that is just driving me nuts and I was wondering if anyone could help me out?...here is the header....now when I run this program I get 52 errors but I just want to start with the first one and then work on it and see if I can contiune!...the first error is that it says: error C2804: binary 'operator <' has too many parameters
error C2333: 'CNum:perator`<'' : error in function declaration; skipping function...can anyone please explain to me why?...Thank you very much in advance and sorry to trouble you all if this is really simple:

Code:

#ifndef __CNUM_H__
#define __CNUM_H__

#include <iostream>

class CNum
{
	private:
		float R;
		float I;

	public:

  		
  		friend std::ostream& operator <(std::ostream & out, CNum& X);
   		friend std::istream& operator >(std::istream & in, CNum& X);
		
		
		
		

		CNum operator+(const CNum& B) const; 

		
		CNum& operator++();    			


std::ostream& operator <(std::ostream & out, CNum& X)
{
	std::out<< "("<< X.R <<"," << X.I<<")"<<"\n";
 	return out;
}
		  			
std::istream& operator >(std::istream & in, CNum& X)
{
	std::in >> X.R >> X.I;
      return in;
}	
};

#endif

try putting the operator functions outside of the class declaration, since they are not part of the class

edit: there are two ways of doing operator overloads. The first is as an instance method of a class, then the first argument of the operator is the instance itself, and the other operands are parameters so e.g. for < it would only need one other operand as a parameter. The second is as a global function not part of a class, then it would require all the operands as parameters. This is an example of the second type, since the first operand is istream / ostream, and we are not messing with those classes; so we put them as global functions.

Thanks spoon for your help
