VARIABLES ND CONSTANTS

Before learning to write programs in QBasic, you should know about Variables and canstants in

QBasic

Constants

An item with a fixed value is called a constant. Constants do not change their values during the

ejection of a program.

Variables

Variable is a name which an contain a value. Variables are items which may change their values

during the executing of a program.

QBasic, variables are of two types:

String variable                                  numeric variables

String Variables

Type of variable contains values within the double quotes (“”). A $ (dollar) sing has to be added

how the string variable.

           STRING                                $ “I am String”

Numeric variables
This type of variable contains numbers. The symbols are not compulsory while writing simple
programs. So, in the programs we use all numeric variables without any symbols.
