Hi,

Here is the answer.

An argument can be passed in two ways. They are passing by value and passing by reference.

Passing by value: This method copies the value of an argument into the formal parameter of the subroutine.

Passing by reference: In this method, a reference to an argument (not the value of the argument) is passed to the parameter.

Thanks.
