Call Stack

Section titled “Call Stack”

Introduction

Section titled “Introduction”

The call stack is a data structure that tracks the execution of function calls. It operates as Last In, First Out (LIFO) — the most recently called function is the first to complete.

Learning Objectives

Section titled “Learning Objectives”
  • Understand how the call stack tracks function execution
  • Identify stack frames and their components
  • Recognize and avoid stack overflow
  • Trace execution through the call stack
