Stack Memory
In plain terms
Memory region for function calls and local variables.
Going deeper
The stack stores function call frames, parameters, and local variables in last-in-first-out order, automatically managed. It grows and shrinks with calls.
Under the hood
Fast allocation but limited size; deep recursion causes stack overflow, contrasts with the flexible heap.
Examples
Function calls, local variables, recursion, stack overflow, call frames.
Think of it like...
Like a stack of trays added and removed from the top as you call and return.
