Left shift bit operator overloading - c++

Question

Hello guys,
I am trying to overload the left shift bit operator, <<, to do something like:
char value[] = "Hello";
value << 2;
when doing this I would like to have it printed like: "val", so to delete the last two character; My problem is I can't manage to declare my overloading function properly.
My code is:
//the .h file
#pragma once
#include <iostream>
class Operators
{
public:
char *word;
int number;
Operators(void);
Operators(char str[], int num);
~Operators(void);
void Print(void);
friend char & operator<<(char &stream, int &nr);
};
#include "StdAfx.h"
#include "Operators.h"
#include <iostream>
Operators::Operators(void)
{
word = "";
number = 0;
}
Operators::Operators(char *str, int num)
{
word = str;
number = num;
}
Operators::~Operators(void)
{
}
void Operators::Print(void)
{
printf("\nThe String: %s", word);
}
friend char & operator<<(char &stream, int &nr)
{
return stream;
}
// Operator_Overloading.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "Operators.h"
#include <conio.h>
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
char value[] = "Hello";
Operators op(value, 2);
op.Print();
_getch();
return 0;
}

You cannot overload any of the operators if they don't involve, at least, one user defined type. Your use case involves a char[N] and an int, i.e., you can't overload any operators for these arguments.
