Operators

Does anyone have any good coding examples of overloading the subtraction operator, or any operators. I am suppose to overload the prefix, and postfix, increment and decrement operators, as well as the stream insertion and stream extraction operators.
Any suggestions would be greatly appreciated!!

Try taking a look at this site:
C++ Tutorial - Lesson 25: Operator Overloading, Part I
Hope that helps.

Code:

#include<iosfwd>
#include<algorithm>

class boring
{
int x_;

public:
boring() : x_(0) {}
boring(int x) : x_(x) {}
boring(const boring& rhs) : x_(rhs.x_) {}
boring& operator =(const boring& rhs)
{
  boring temp(*this);
  std::swap (temp.x_ , rhs.x_);
  return *this;
}
boring& operator++() //prefix
{
  ++x_;
  return *this;
}
boring& operator --()
{
  --x_;
  return *this;
}
const boring operator ++(int) //postfix
{
  boring temp(*this);
  ++(*this); // always implement post in terms of pre
  return temp;
}
const boring operator --(int)
{
  boring temp(*this);
  --(*this);
  return temp;
}
const boring operator+( const boring& lhs,const boring& rhs)
{
  return boring( lhs.x_ + rhs.x_ );
}
const boring operator -( const boring& lhs, const boring& rhs)
{
  return boring( lhs.x_ - rhs.x_ );
}
std::ostream& print( std::ostream& os )const
{
  os<<x_;
  return os;
}
std::istream& get( std::istream& is)
{
  is>>x_;
  return is;
}
std::ostream& operator <<( std::ostream& os, const boring& b)
{
  return b.print(os);
}
std::istream& operator >>( std::istream& is, boring& b)
{
  return b.get(os);
}
};
