Functions in C++

Course Overview

This course is structured to provide a thorough exploration of functions in C++, starting from the very basics of function definition and declaration to more complex aspects like recursion and passing objects to functions. By the end of this course, you will have a solid understanding of how functions work in C++, how they can be optimized, and how to apply them in real-world programming scenarios.

What You Will Learn

• C++ Functions: Introduction:
  Get acquainted with the basic concepts of functions in C++, including why they are used and how they enhance the modularity and efficiency of your code.
• Definition and Declaration:
  Learn how to define and declare functions, understanding the syntax and structure essential for creating functional C++ code.
• Function Parameters:
  Dive into the different ways of passing data to functions, including passing by value, reference, and with default parameters.
• Static Functions:
  Explore the concept of static functions and how they maintain internal state information across function calls without instantiation of an object.
