Answer Posted / sruthi
Call by reference means address of var is passed to sub pgm.
The modifications on the passed vars in sub pgm will be
effected in main pgm.
call by content means value of the var is passed to sub pgm.
The modifications on the passed vars in sub pgm will not be
effected in main pgm. that is local to sub pgm.
