Operator overloading question

I have a class written, and i need to overload the operator + for it, so it just sums everything up really.

Code:

Folder f1;
f1.add_entry("name","post");
// f1.name[0] = "name"
// f1.post[0] = "post"
//both arrays have more space


Folder f2;
f2.add_entry("name2","post2");
// f2.name[0] = "name2"
// f2.post[0] = "post2"
//both arrays have more space.

Folder f3;

So i need:

Code:

f3 = f1 + f2;

So f3 then contains all the info from f1 and f2.


How do i write that function, i'm lost with unary operator overloading...

BTW, the variables in the classes are mostly strings with a bool and a double in there.

Create a member function called "operator +" which returns an object of the same type as the class, and which receives as a parameter any type that you want.

Code:

class MyClass;
{
public:
   MyClass operator+(int rValue);
   MyClass operator+(double rValue);
   MyClass operator+(const MyClass& rValue);
};
