C++ Developer - Function Prototypes and Definitions

The video tutorial introduces the concept of functions in C programming, focusing on function prototypes and definitions. It explains the importance of organizing code by placing function prototypes above the main function and definitions below. The tutorial includes a practical project to create and test a function, emphasizing the need for function declarations before use. Key terminology such as function prototypes, definitions, and calling functions are covered. A challenge is presented to create a simple function, reinforcing the learning. The session concludes with a summary and a preview of the next lecture on functions with different return types and parameters.

What happens if you try to call a function without declaring its prototype first?

How do you invoke a function in C, and what is meant by 'calling' a function?

What is the role of the return type in a function, and how does it affect function usage?
