What is a Quiz Question?

You can see a few examples of Quiz Questions here.  A Quiz Question consists of the question itself, 5 multiple choices, and the solution with an explanation.   

Imagining/creating a quiz question is relatively easy -  even ChatGPT can do it.  Here's what ChatGPT came up with when I asked for a fun quiz question for Embedded Systems engineers:

# Question

What is the term used to describe the order of bytes in a multi-byte data type in an embedded system?

# Choices

• A) Alignment
• B) Endianness
• C) Bitness
• D) Bytecode
• E) None of the above

# Solution & Explanation

The correct answer is B) Endianness.

Endianness is the term used to describe the order of bytes in a multi-byte data type, such as a 16-bit integer or a 32-bit float. There are two main types of endianness: big-endian and little-endian. In big-endian systems, the most significant byte is stored first, while in little-endian systems, the least significant byte is stored first. For example, the hexadecimal number 0x1234 would be stored as 0x12 0x34 in big-endian systems and as 0x34 0x12 in little-endian systems.

Endianness is an important concept in embedded systems because different processors and devices may use different endianness formats. This can cause problems when transferring data between them or when reading data from memory. Therefore, embedded system programmers need to be aware of the endianness of their system and use appropriate methods to convert data between different formats if needed.

Not bad! But we think you can do better than ChatGPT.

The ideal Quiz Question is catchy and educational at the same time.

By catchy, I mean hard to resist.  I'm sure you've stumbled on brain teasers on Social Media that you couldn't resist trying to solve.  For instance, chances are that you'll feel the urge to try and solve the following logic puzzle:

(in case you'd like the solution, it is 645, and the explanation is that you need to add the sum and product of the four digits).

Creating catchy Quiz Questions for the Embedded Systems community is more tricky. One of the quiz questions we posted a while ago did pretty well with almost 3000 individuals who gave it a shot.:

Predict the output of: 

#include <stdio.h>
#define x 2+3
int main()
{
    int y;
    y = x*x*x;
    printf("%d", y);
    return 0;
}

Why did this question perform well?  It wasn't perfect but we think it has these qualities:
