How c++ allocate memory for class member functions?

I am curious how c++ allocate memory for class member function.

Then, I create two objects of class A; let say A and B. I know that both objects will have their own memory for storing n variable. But, how's about function one? Will a compiler allocate two blocks of memory; one for function one of A and the other one for function one of B??

class A
{
int n;
void function1() {}
}```

No, there is only one instance of the function code. The this pointer that gets passed to that function is how it knows what object it's working with.
