A Level Computer Science Visual Basic Notes Pdf Array Data Visual basic has different data types to specify the kind of variable used. string data types store text, boolean is true false, and numeric types like byte and integer store different ranges of whole numbers. decimal types like single and double store varying levels of precision. The following table shows the visual basic data types, their supporting common language runtime types, their nominal storage allocation, and their value ranges.
Visual Basic Pdf To use variables we must tell vb what data type our variables should be. we do this using the dim statement, which “dimensions” a storage location for us using the format:. The document provides an overview of variables and data types in visual basic, explaining the concept of variables, their declaration, and the importance of explicit versus implicit declaration.
