C++ Function prototypes


	Lesson 2 Objective	Function prototypes Re-code C program which uses traditional C function syntax
		The syntax of functions in C++ inspired the function prototype syntax found in ANSI C. A C++ function lists the types of the function's parameters inside the header parentheses. Explicitly listing the type and number of arguments makes strong type checking and assignment-compatible conversions possible. This list of a function's arguments in the header parentheses is called the function's signature. Example Let us consider a function `min` that determines the minimum of two numbers. It's prototype would be: int min(int, int); Both the function return type and the argument list types are explicitly mentioned. The definition of `min()` that occurs in the file must match this declaration. The function prototype can also include the identifier names of the arguments. In the case of `min()`, this would be: int min(int x, int y); C++ also allows unspecified argument lists.
