What is the use of consonant in QBASIC ? Answer me in short and easy answer.

Digiron [165]

Answer:

See Explanation

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 $\pi$ in your program.

Its value is $\pi = 3.142$

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

<em>The above represents a numeric constant. QBasic also have string constants.</em>
