=== Stack ===
Variables declared in procedures and functions are allocated on the stack.<br>
Their scope is local to the respective procedure/function and their memory is freed with the end of the procedure/function.
=== Heap ===
Dynamicly created objects (dynamic arrays, class instantiations, ...) are allocated on the heap.<br>
Their creation and destruction is done explicitly.
