Every stack you trace today is one less crash you're debugging blind tomorrow.
A BCA student asks Sumantrak
“explain why Stack is called a LIFO structure”
LIFO means Last-In, First-Out — the last element pushed onto the stack is always the first one popped, like a stack of plates you can only take from the top. Viva tip: examiners immediately follow up with "give a real example" — function call stacks, undo operations in editors, and browser back-buttons all work this way because whatever happened most recently needs to unwind first.
