Notes

*(char*)0 = 0:
- 1, Casting Zero to a Pointer: (char*)0 casts the integer 0 to a pointer, pointing to memory address 0.
- 2, Dereferencing: The * operator is then used to dereference this pointer, meaning we're trying to access the value at this memory location.
- 3, Writing to Address 0: The whole expression attempts to assign 0 to this location.
