Talk:Mutator method

In computer science the mutator method is a method that changes the value of the argument variables.

Wrong, the object the function is called on is changed, not the variables that are passed as argumetns to the method/function

In the call-by-value form of argument passing, a reference or pointer to the data needs to be passed.

Wrong, no explicit need for that, just because its a mutator. And the example also shows pass-by-value of an integer
