Answer:
They are not always right or the most accurate.
Explanation:
Judgments and decisions based on heuristics are simply good enough to satisfy a pressing need in situations of uncertainty, where information is incomplete.
Answer:

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
in your program.
Its value is ![\pi = 3.142](https://tex.z-dn.net/?f=%5Cpi%20%3D%203.142)
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>
