Implicit pointer conversion

[xander333]

Hello,

Say we have a Derived pointer. A function takes a Base pointer.
Can I do this?

void test(Base* ptr)
{

}
Derived* obj;
test(obj);

I don't have access to a compiler here so I cant test it out :)

Nvm I found an online C++ interpreter and it works :)

FWIW, this is one of the fundamentals of polymorphism (so, a function that takes a 'Shape *' can take a 'Square *' if Square derives from Shape). You can also see similar behavior with references

void test(Base & input)
{

}
Derived obj;
test(obj);
