What is Memory Stack?

A memory stack is a fundamental data structure in computer science that operates on the Last-In, First-Out (LIFO) principle. Elements are added (pushed) onto the top of the stack and removed (popped) from the top. Memory stacks are commonly used for function call management, expression evaluation, and managing program memory. In function calls, the return address and local variables are pushed onto the stack when a function is called, and popped off when the function returns. This ensures proper program flow. They are also used in compilers and interpreters for expression parsing and evaluation.
