In Call by value we simply passes the variable to the
function but in CAll by reference we actually pass the
memory address where the variable we want to pass is stored.

In call by value,the function arguements will be duplicated
and sent to the called function from the function which is
calling it.
In call by reference ,the function arguements' address will
be passed to the called function by the calling function.
This method is the best practice since address is passed
rather than value.

Answer / rahul
In call by value function, the value of the actual
parameters or arguments from calling function is passed on
to the called functions i.e. actual value is copied into the
formal parameters of called function. The arguments passed
may be variables of any data type or constants also.
In call by reference, the address of actual parameters are
passed on to the called functions from calling functions.
So, the values stored in these memory locations can be
altered, which is reflected in calling functions also.
