What is a variable?
In GCSE Computer Science, a variable is a named memory location that holds data that can change during the execution of a program. Variables can store a variety of different types of data such as integers, strings or boolean values.
To store data in a variable, the process of assignment is used. A variable will have an identifier (name) and will then be assigned a value. Some programming languages will also declare the data type of the variable. Some examples of declaring a variable and assigning it a string value of “Save My Exams” have been included below in various languages:
Language | Code |
|---|---|
Python | name = "Save My Exams" |
Visual Basic | Dim name As String name = "Save My Exams" |
Java | String name = "Save My Exams"; |
Pseudocode | name ← "Save My Exams" |
