    Definition of Variable:

    A variable is a symbol that represents a number, a string of characters, or a location in memory.

    A variable is a symbol that represents a number, a string of characters, or a location in memory. When you assign a value to a variable, you are giving that variable a name so that you can refer to it later.

    When you assign a value to a variable, you are giving that variable a name so that you can refer to it later. A variable can be used to store any type of information, including numbers, strings of characters, and arrays of data.

    A variable can be used to store any type of information, including numbers, strings of characters, and arrays of data. A variable can be used to store the result of an equation or a function.

    Difference between Constant and Variables

    A constant is a value that does not change, while a variable is a value that can change.

    Points to remember with the Difference between Constants and Variables

    1. Constants are unchanging, while variables can change.

    2. Constants have a specific value, while variables can have any value.

    3. Constants are usually named after the value they hold, while variables are usually named after the type of data they store.

    4. Constants are always written in all caps, while variables are always written in lowercase.

    5. Constants are always assigned a value when they are created, while variables can be assigned a value or left unassigned.
