This illustrates it (not on the Palm...):
#include <stdlib.h>
#include <iostream.h>
class A {
public:
A() {
cout << "A::A()" << endl;
}
};
class B {
public:
B() {
cout << "B::B()" << endl;
}
B(const A &a) {
cout << "B::B(A&)" << endl;
}
};
void func(B b) {
cout << "func(b)" << endl;
}
int main(int argc, const char *argv[])
{
A a;
func(a);
return 0;
}
