Posting Etiquette

  1. Ask the main part of your question in the title. This should be concise but informative.

  2. Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.

  3. Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.

  4. Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

I saw one example

int x = 10;
int y = 5;

bool isGreater = x > y;

printf("%d", isGreater);

But I could write this

int x = 10;
int y = 5;

printf("%d", x > y);

I am a complete beginner and I have no real reason why I would or would not want to deal with boolean variables, but I want to understand their raison d'être.

Okay, now... variableA = 1 (true) and variableB = 42 (true). Suppose we want to compare the values of them to see if they're the same or different. A simple check of if variableA == variableB will return False, because while they're both set to 'true', they're set to different values of 'true'. It could get problematic and become a way to introduce really weird bugs.
