How many ways can an argument
be passed to a subroutine and explain them?
- 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.
