What does full code mean because when i was looking at my medical chart today it said full code by my name

This means hospital right?

I've never been admitted to one so have never seen a 'medical chart'.

As per Google:
Full Code" on a medical chart means that if a patient's breathing or heart stops, the medical team will perform all possible life-saving, resuscitative measures. This includes, but is not limited to, cardiopulmonary resuscitation (CPR), electrical shocks (defibrillation), intubation, and mechanical ventilation to sustain

It means they will do everything possible to save you. CPR and advanced CPR and whatever they deem necessary .
