Answer / 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.

'Call by Content' means value of the variable is passed to
the subprogram and after modification on this variable in
sub-program will not effected in main program.
'Call by Address' is opposite to above. Here address of the
variable is pass to the sub-program at the time of call and
modification on this passed variable in sub-prog will be
effected in main program.

Answer / shiva
call by reference passes address of variable to the subprogram
and any changes to this variable will affect the main program
this is bcoz they have allocated the same memory..
whereas in call by content the value of the variable is
passed to the subprogram and any changes to that variable
does not affect the main pprogram..this is bcoz they have
allocated seperate memories.......
