minus-square@[email protected]linkfedilinkEnglish2•edit-21 year agoIsn’t NULL a macro in C for 0? So doesn’t that mean these items are free?
minus-square@[email protected]linkfedilink2•1 year agoIn a way it’s still the same with more modern languages. Especially OOP, setting an object to Null is just setting the address pointer to to 0x00000000. Hence NullPointerException / NullReferenceException or similar, depending on the language.
