Answer 2

Variable is a name given to a storage area

Explanation:

• A variable is nothing but a name given to a storage area that can be controlled by our programs. Every variable has a particular form that specifies the size and layout of the memory of the variable; the number of values that can be stored in that memory; and the collection of operations that can be applied to the variable.
• A variable name can consist of letters, digits, and underscore characters. It needs either to start with a letter or an underscore. A variable should not declare with space, ideally should be of 14-15 characters, and should not use reserved words.
