Answer Posted / 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.......
