operator overloading

how do you perform operator overloading using binary operators?

Yes, Yes it is a homework problem, it is just that i cant understand overloading bit..

isn't this a binary operator statement -->

a*b;
a+b; etc

how do you overload that?


*edit*
post# 69 yay!!

operator overloading is discussed in the following link:

http://www.stud.fim.ntnu.no/~oystesk/CPP/htm/ch10.htm

The simplist declaration of an overloaded binary operator for class T would be something like this:

class T
{
public:
//default constructor assigns value of 0 to data
//single parameter cconstructor assigns input to data
int data;
T T::operator+(const T &)
};

with definition like this:

T T::operator+(const T & rhs)
{
T temp;
temp.data = data + rhs.data;
return (temp);
}

and used in program like this:

int main()
{
T example1(3), example2(18);
T result;
result = example1 + example2;
cout << result.data;
return 0;
}

But read the chapter for a more sophisticated discussion and other examples.

great link Unregistered, but is there a way to do it without using of classes,constructors etc

No, you can't create global overloads for the binary operators.

if you do not want it to be a class member.
try this: friend T operator + (int n, T whatever )
