24 Questions
In C++, what does short-circuit evaluation refer to?
Skipping the evaluation of the second expression if the first guarantees a result
How is evaluating boolean expressions similar to evaluating arithmetic expressions?
Boolean expressions use different operators but get T/F outcomes
Why does C++ use short-circuit evaluation for boolean expressions?
To save time by skipping unnecessary evaluations
When does C++ decide to not check the second expression in a boolean 'and' operation?
If the first expression is false
Which type of evaluation checks every expression in a boolean statement, unlike short-circuit evaluation?
Complete evaluation
Why might short-circuit evaluation be preferred in certain cases?
'Complete evaluation' is often slower
How many possible values can a single binary bit have?
2
What is the relationship between bytes and bits in a computer system?

Why is it important to consider the bit size when storing data?
To avoid exceeding memory limits
How does the Legend of Zelda game (1986) demonstrate size limitations in data storage?
By restricting the number of rupees a character can hold due to bit constraints
What makes emojis unique when it comes to Unicode encoding?
'Emojis' are encoded under Unicode along with scripts from various languages
