What is the disadvantage of a call by reference?

 Answer:

During a call by reference damage or loss of data is not restricted to the subroutine, but will instantly lead to changes to the original data objects.

Call by reference passes the address of the argument into the required subroutine, thenh when it is altered in the subroutine, its altered value will overwrite the original
argument value.
