Function Parameters and Return Values

Summary

This tutorial explains how to pass parameters to functions and return values in C++. It builds upon a previous tutorial covering function basics, function prototyping, and usage. The example focuses on a 'display' function, which takes two integer parameters and returns no value (void). The tutorial emphasizes specifying parameter data types during function prototyping. The next step involves defining the function's body after the main function.
