Answer / prakash

both are same, this should be a difference between call by
reference and by value/content.
Here we send the address of he data in first case and the
value/content in second case.

Answer / sridevi

Call by value will not return the data back to the calling
program
Call by reference shares the common storage for the
variables used between the calling and called program and
the called program returns the data back to the calling
program through by reference

Answer / michael

call by reference:
pass pointer to data
call by content:
copy data into temporary, pass pointer to temporary
call by value:

passed data value

CALL BY REFERENCE: we will send the address of he data.

Answer / kapil arya

it takes more time in camparison of Call by value.
