Answer Posted / prateek g
The call by value system copies the actual parameters to
actual parameters and then uses them i.e. the function
creates its own copy of values, any change in
these values will not be reflected
in the original values.
The call by reference system refers the actual parameters
i.e. these doesn’t creates a copy of original parameters,
any change in these parameters will be reflected back in
original parameters.
