Hi friends,

Below program is so simple if you are familiar with operator overloading then it is lot more easy understand,
the idea is that by overloading istream and ostream operator we can directly call cout and cin  the standard  C++ liabrary function  for input/output operation with user defined data data types that is class objeccts.

First it is useful to have a look at this two operator overloading programs:

Now if  you have understand above two program then now it easy quite easy for you to understand this program.

Let's look at how istream and istrem operator overloading function are declared:

syntax like this:

return-type   operator operator-name(parameter-list);

look below at declaration:

ostream &operator<<(ostream &tcout,matrix &m)



  istream &operator>>(istream &tcin,matrix &m)


DOWNLOAD sourcecode  from here:

complete code is look like this:


#include <iostream.h>
#include <conio.h>


class matrix
{
private:
 int a;
public:
 friend ostream &operator<<(ostream &tcout,matrix &m);
 friend istream &operator>>(istream &tcin,matrix &m);


};
  ostream &operator<<(ostream &tcout,matrix &m)
{
   tcout<<m.a;
   return tcout;
}




  istream &operator>>(istream &tcin,matrix &m)
{
   tcin>>m.a;
   return tcin;
}


void main()
{
   matrix m;
   clrscr();
   cout<<"Enter integer value :";
   cin>>m;
   cout<<"You entered:"<<endl;
   cout<<m;
   getch();


}
