/* INPUT: Enter any variable name . OUTPUT:Program will show if entered name is valid variable name in C++ or not . Variable naming conditions in C++ are as follows : #1. A variable name should not start with number. #2. It should not contain special charecters eg. ;@:?.!\/%&*| etc. #3. It should not have any white spaces . #4.
