In programming, a variable is a named storage location in memory that can hold a value or data. It’s like a container that can hold different values at different times during the execution of a program.
When you declare a variable, you give it a name and a data type. The data type determines what type of data the variable can hold, such as numbers, characters, or Boolean values. You can assign a value to a variable using the assignment operator (=), and you can also update the value of a variable by assigning a new value to it.
Variables are used in programming to store and manipulate data, and they play a crucial role in many programming languages. They are used to keep track of information, perform calculations, and make decisions based on the data stored in them.
