This is OK, but it somehow cages you into some limitations, such as you must call the exact variable name to access its value, you cannot easily cycle between them, you cannot tell the number of values so quickly, and more. For such operations, there is an appropriate structure, which comes at hand and allows us to work on the values as a single entity--this ...
