• Variables are used for displaying data, while constants are used for calculations.

How can you design a user interface in Visual Basic?

• Write the code manually in Visual Basic

• Use a separate software to design the interface and import it to Visual Basic

• Use the drag-and-drop interface builder in Visual Basic

• Hire a professional designer to create the user interface

What is the purpose of using data types in Visual Basic?

• To define the type of data that a variable can hold and for efficient memory allocation and type checking.

• To make the code more confusing

• To slow down the program

• To increase the chances of errors

What are the rules for naming variables and constants in Visual Basic?

• Variables and constants must start with a number and can contain special characters

• Variables and constants must be all uppercase
