Explanation:
I'll assume the question is about the use of constants in QBasic because consonants do not have any special function or usage in QBasic.
In simple terms: In QBasic, constants are used to represent elements that do not change in value during program execution.
Take for instance, you intend to use [tex]\pi[/tex] in your program.
Its value is [tex]\pi = 3.142[/tex]
So, 3.142 will always be a constant in your program. One of the ways it can be used in a program is:
10 LET PI = 3.142
The above represents a numeric constant. QBasic also have string constants.
