In this paper we describe variable and expression declaration, declaration of range variable (array etc.) in c ++ox. These all concepts are defined in c ++ but in this we face some problems. Like when we are declaring any variable then we have to mansion data type in front of the variable unless it not properly read by compiler. Second in array if we wants to store and retrieve the value then we can access it from its index value in other word we have to mansion array’s index value by iterative statement. In this paper we show that these above concept is run in easy way and remove all the problem in c ++ox
