Which of the following is the definition of a variable?

• A container which is used to store values such as the number of attempts a person tries to log on to a network.
• A language that is similar to a real programming language, but is easier for humans to understand although it doesn’t actually run on a computer. It can easily be converted to a regular programming language.
• A value that cannot be altered by the program during normal execution: the value stays the same. 
• Messages to explain to others, and often to remind yourself, what the code is intended to do.
