+ operator overload

You need to make the operator-overload a global function, as opposed to a class member function.

class A { ... };

A operator+(const char* lhs, const A &rhs) { ... }

"Sneftel is correct, if rather vulgar." --Flarelocke

Making the overload a friend of your class can also be a good idea, depending exactly on what it is you want to do.

You can''t, and should therefore write:

''meat = S("hens") + cows;''

instead of just
''meat = "hens" + cows;''

Sneftel is right, the only way to overload something like that is thru a global operator overload.

You can define a function as a friend function by placing it in the class you want to be friends with, and putting the word "friend" in front of it.

Ex.

class A 
{
 ... 
public:

// this function is still global even tho it is in a class
friend A operator+(const char* lhs, const A &rhs); // friend prototype
};

// global overloaded + operator
A operator+(const char* lhs, const A &rhs) { ... }
