Thanks for your explanation. Yeah I can see how you'd need to state the types again for the possibility that you'd be overloading functions. Otherwise it wouldn't know which function definition went with which prototype. I really appreciate the help guys. Topic...
A function prototype, also known as a function declaration, is a way to inform the C++ compiler about the existence of a function before its actual definition. This is particularly useful when you want to call a function before defining it or when you have multiple functions in different files...
A function declaration precedes the function definition and specifies the name, return type, storage class, and other attributes of a function. To be a prototype, the function declaration must also establish types and identifiers for the function's arguments. ...
since a function identifier evaluates to a pointer expression. To use a function identifier in this way, the function must be declared or defined before the identifier is used; otherwise, the identifier is not recognized. In this case, a prototype forworkis given at the beginning of themainfu...

While the prototype may be created professionally, it's not meant to be a final product but rather a tool that can be altered and improved before being mass produced. Creating a prototype is a step in the product development process and can be used to get company support for a product or...
