          • What is the difference between a variable and a constant?

          So, what is a variable? In simple terms, a variable is a name given to a value that can be changed or manipulated within a program. Think of a variable like a container that holds a specific value, which can be modified as needed. Variables are the building blocks of code, and they play a crucial role in storing and manipulating data. For example, when you create a variable named "age" and assign it the value "25," you can use that variable in subsequent lines of code to perform calculations or print the value.

        Common questions

      • Variables can only store numbers; they can store any data type.

        • No, a variable can only store one value at a time. However, you can use an array or a list to store multiple values.

        However, there are also realistic risks associated with variables, such as:
