How do you write an average function in C++?

You can also calculate average using variable number of arguments. The principle of this a function that an unknown number of arguments is stored in a stack and we can take them. And you can using this function like: double av1 = average( 5, 3.0, 1.5, 5.0, 1.0, 2.0 ); double av2 = average( 2, 3.0, 1.5 );
