A method that takes a variable number of arguments is a varargs method.
Prior to JDK 5, variable-length arguments could be handled two ways.
One using overloaded method(one for each) and another put the arguments into an array, and then pass this array to the method.It is possible to pass a variable number of arguments to a method.
However, there are some restrictions: The variable number of parameters must all be the same type.
They are treated as an array within the method.25 fév. 2010
What is the variable number of arguments?
The variable number of arguments in C++ is a feature that permits a function to accept any number of arguments.
This type of function is called variadic functions.
Functions with a variable number of arguments in C++ can be easily implemented using a vector or an array if all the arguments are the same type.
