Functions remain an important construct for code modularization and reuse in C++, even though C++ is an object-oriented language. Learn how to use functions in C++, focusing on free functions, and examine the distinction between declaring a function, where you specify the function's signature, return type, and name; defining a function, where you create the body of a function; and invoking the function. Then, explore the semantics of passing parameters by value to C++ functions. Finally, compare pass-by-reference semantics to pass-by-value semantics and investigate the differences. Upon completion of this course, you will be able to use pass-by-value and pass-by-reference semantics in the context of function invocation in C++.
