What is variables?
- In a computer programme, values are stored in memory locations that are given names called variables. An assigned value is given to a specified data unit called a variable. Virtually all programming languages make use of variables, which can be expressed in a variety of ways depending on the script or software creator.
- The type of data a variable carries is indicated by its name. Variables get their moniker because the data they represent can change while the operations on them stay the same.
