Thread: Functions of arbitrary parameters

While browsing a c++ faq I came across this comparison with C and found something I either didn't know or am reading wrong.

Code:

[6.11] Is C++ backward compatible with ANSI/ISO C?

Almost.

C++ is as close as possible to compatible with C, but no closer. In practice, the major difference is that C++ requires prototypes, and that f() declares a function that takes no parameters (in C, a function declared using f() can be passed an arbitrary number of parameters of arbitrary types).

Is this saying that defining a function as something like

Code:

void f(); 

/*...*/

void f(){
/*...*/
}

would let one do something like

Code:

f(45, 100);

or

Code:

f("string", NUM, 2);

or whatever? If so how do you refer to each argument in the function?

Oh I see. Thanks
