C++ Developer - Function Overloading

The video tutorial covers scopes and variable lifetimes, focusing on global, local, and static variables. It introduces function overloading, a feature in C, and guides viewers through creating a project to demonstrate this concept. The tutorial includes a challenge to add a new function overload and provides a solution walkthrough, emphasizing the importance of function signatures in distinguishing overloads.

In the example provided, what are the expected outputs when calling the overloaded functions with specific parameters?

Discuss the role of the return type in function signatures and its impact on function overloading.

What would happen if two functions had the same name and the same parameters but different return types?
