info on pointer operators??

Hello, i've come across this problem and got curious, after fiddling with the code for a while, i got operator working for non - pointer class,

like

MyClass a,b;
a += b;


but what fails are the pointers, (the below)

MyClass *a, *b;
a += b;

this fails with the error, invalid operand of types.


How do you get the above working? any hint, suggestion, or solution will be appreciated

Well a and b are pointers, so:

Code:

---

a += b;

---

is adding two pointers, not the contents of the class. What you want is:

Code:

---

*a += *b;

---

But this is only guaranteed to work when a and b are pointing to allocated memory. It may work by accident, but to be correct you'd need to allocate memory first for both pointers:

Code:

---

a = new MyClass;
b = new MyClass;

*a += *b;

---

And once you're done with a and b, you'd need to deallocate the memory:

Code:

---

delete a;
delete b;
