Memory allocation in programming generally occurs in two areas: the stack and the heap. Both of these memory areas have unique characteristics and are used for different purposes.
- Size: The stack is usually smaller in size compared to the heap.
- Speed: Stack allocation is faster because it is managed by the CPU and follows a Last In, First Out (LIFO) order.
- Lifetime: Variables on the stack have a very short lifetime. They are automatically deallocated when the function that created them returns.
