Variables and Data Types
The representation of real-time components of a problem into variables allows us to represent the problem in such a way that it can be solved by a computer program.
Variables are labels that are used to represent values stored in computer memory. Declaration of variables in a program is essential as the correct amount of space in memory is allocated by the compiler. The value of the variable can be changed during execution.
Constants are labels that are used to represent values stored in computer memory that remain unchanged during the execution of a program.
This GCSE Computer Science module introduces variables and data types to your students, explaining:
- What they are
- Different data types
- How to estimate size of a data file
- Input and Output
