the beginning of a C++ file (usually in a header file, .h, or directly in the source file, .cpp) before you use or call the function. It tells the compiler what to expect in terms of the function's signature. When you later define the function, it must match the prototype exactly....
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....
A function prototype is a declaration of the function that informs the program about the number and kind of parameters, as well as the type of value the function will return. One incredibly helpful aspect of C++ functions is function prototyping. A function prototype provides information, such as...
A function prototype describes the function interface to the compiler by giving details such as the number and type of arguments and the type of return values.The prototype declaration looks just like a function definition, except that it has no body, i.e., its code is missing. This is ...
A 'Function Prototype' is a declaration that informs the compiler about the type of arguments and the return type of a function in a computer program. It is similar to the function header and is necessary when there are multiple functions in a program. ...

Function prototype and function definition in C++ programming come into play while working with user-defined functions. User-defined functions are functions defined by the user as per the requirement of the program or to solve a given set of queries. ...
If any programmer wants to use some functions in future times, they only need to check the prototype of the functions and don’t need to go into detail about function definitions. Lastly, the template code should also be in the header file. The CPP file now defines the function declared ...

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...
