Answer / nakul sharma
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 reference we provide address of another variable
In call by value we directly assigned value to variable

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.

Answer / sangeetha
In call by value, the changes made in the formal arguments
does not affect the actual argument
In call by reference, the changes made in the formal
arguments does affect the actual argument

There are N egg baskets and the number of eggs in each basket is a known quantity. Two players take turns to remove these eggs from the baskets. On each turn, a player must remove at least one egg, and may remove any number of eggs provided they all belong to the same basket. The player picking the last egg(s) wins the game. If you are allowed to decide who is going to start first, what mathematical function would you use to decide so that you end up on the winning side? Upload a C program to demonstrate the behaviour of the game.
