This Pointer Trick Crashed My Code in a Real Interview | C Trap #4 #coding #dsa #90dayschallenge

It didn't. No error, no warning — just silent wrong behavior.

This is one of the most common C interview traps —
pointers are passed by value, not by reference.

This is the kind of thing your interviewer
knows... and assumes you don't.
