    Study Notes

    Stack Data Structure

    • A stack is an essential data structure for the operation of a computer program with subroutines.
    • When an item is added to a stack, also known as pushing, it is added to the top of the stack.
    • A stack is a Last-In-First-Out (LIFO) data structure, meaning the last item added is the first item to be removed.
    • Attempting to push an item onto a full stack results in a stack overflow, which can cause program errors or crashes.
    • A stack pointer is a register that keeps track of the top of the stack, facilitating the pushing and popping of items.
