Variables and Data types
Variables
When we make any program we need some place to temporarily store different types of data related to that program to perform different operations on it. That’s why we need variables to store data temporarily in it. You can’t store data permanently in variables because variables work in Random Access Memory. To store data permanently on hard disk we need files for it.
Data Types
Data type of any variable is the type of the data which decides that what kind of data can be store in variables. There are many data types like “integer” for storing numbers, “character” for storing characters, “strings” to store strings etc.
Variable in Mathematics
Variables in Maths is a symbol for a value which we don’t know yet. It is usually a letter like Y or B or X etc.
