What is a variable in programming?

• A. A method for performing calculations
• B. A storage location identified by a name that can hold a value
• C. An error in the code
• D. A fixed value used throughout a program

Answer: (B)

In programming, a variable is fundamentally defined as a storage location that is identified by a name and can hold a value. This means that variables act as containers for data, allowing programmers to store and manipulate values throughout their code. When you declare a variable, you assign it a name that can be referenced later to retrieve or modify the value it holds. Variables are essential because they enable dynamic data management; for instance, you can change the value of a variable as your program runs, allowing for more flexible and efficient code. The name associated with a variable allows programmers to easily remember and access the values they need, rather than having to remember specific numbers or strings each time. This understanding of variables is critical for programming because it supports data manipulation, calculations, and concurrency within applications, making it easier to perform complex tasks.
