Answer #1

The following code can not be compiled.

The given code is using the concept of call by reference. The variable reference is passed in call by reference and the changes made to the variable to which the value is passed is reflected back to the previous. But in this scenario a constant value of 4 is passed to the function Addem(). So, instead of the variable reference the value itself is passed and this will provide error.

Hope this helps.
